Which can serve as substrates for atp production?
Answer:
A molecule containing readily 'detachable' phosphate group, an inorganic phosphate, and ADP.
Explanation:
For substrate-level phosphorylation, take glycolysis as an example. Phosphoenolpyruvate has a readily 'detachable phosphate', which with the help of Pyruvate Kinase, is able to be 'attached' to ADP. Both Phosphoenolpyruvate and ADP act as substrates.
For oxidative phosphorylation, take ATP synthase as an example. Due to the proton motive force, the 'motor' of the enzyme allows the knob to spin, changing affinities for ADP, Pi (inorganic phosphate), and ATP. Thus, to produce ATP, ADP and Pi are required as substrates.
In all, a molecule containing readily 'detachable' phosphate group, an inorganic phosphate, and ADP can serve as substrates for ATP production.
The bone marrow begins producing cells in the _____________ month of fetal life.
The bone marrow begins producing cells in the fourth month of fetal life.
Hematopoiesis establishes in the marrow and grows there until, at term. This process starts in the late first trimester when the bones are large enough to contain marrow cavities. Hematopoiesis can move outside of the bone marrow to various organs under conditions of prenatal and neonatal stress.
Between the bone spicules are the hematopoietic components. Both sinusoids and a robust circulatory network are present in the marrow. Pluripotent stem cells are the progenitor cells that give rise to all hematopoietic components and lymphoid cells.

xplain how the chemical breakdown of glucose results in the production of a hydrogen ion concentration gradient across the mitochondrial membrane, as shown
A high-energy electron is transferred along an electron transport chain to the inner mitochondrial membrane. Hydrogen is pumped out of the matrix space by the energy released. Through ATP synthase, the gradient produced by this forces hydrogen back through the membrane. when participating in the crucial process of oxidative phosphorylation.
Only a tiny portion of the glucose's totally free energy is released when it is transformed into pyruvate by the glycolytic process.
The breakdown of glucose into pyruvate within a cell's cytoplasm is known as glycolysis. The final phase of cellular respiration, known as oxidative phosphorylation, generates ATP using an ATP synthase gradient and a hydrogen ion gradient. The majority of the ATP produced during cellular respiration is produced during this process. Pyruvate can diffuse into mitochondria under aerobic conditions, where it enters the citric acid cycle and has reducing equivalents in the forms of NADH and FADH2.

Use a graphic-design program. Using the Insert Image button, insert an image of your food web in the answer space.
The trophic web is the interaction between different organisms in which there is energy transference. In the attached example, we consider plants, caw, rabbit, bird, eagle, mountainlion, and fungi.
Note: Since you did not detailed the organisms you identified in part B, I will define what a trophic web is, and propose an example for you to understand.
What is a trophic web?The trophic web is the interaction between different organisms involving transference of energy when some of them feed on the other ones.
The ones placed at lower levels pass energy to the ones at the higher levels.
Organisms at each level feed on the preceding one and become food for the next one.
• The first link corresponds to a producer organism -autotroph-.
• The following links are the consumers -heterotrophs-: herbivores and carnivores.
• The last links are the decomposers that degrade organic matter from dead organisms.
Because it is a web, all organisms are in equilibrium until a change occurs. When a sudden change affects any of the involved links, there can be a cascade effect on the web.
Any change in a link population size (increasing or decreasing) will affect the superior links and the immediately anterior link.
Example.
To make the trophic web, first, you need to define the position of each of the organisms on the web.
Producer → this is the autotroph organism that takes energy from the sun or any other inorganic source → An example of this is any plant.
Consumers → heterotroph
⇒ Herbivores → These are the animals that feed on any part of the plants → Let us say we have a caw, a rabbit, and a bird.
⇒ Carnivores → These are the animals that feed on herbivores → Let us say a mountain lion and an eagle.
Decomposer → detritivorous organisms that take energy from dead matter → Fungi
So, our organisms are
plants, caw, rabbit, bird, mountain lion, and eagleFungiPlants directly provide energy to the caw, the rabbit, and the bird.
Plant >> Caw, Rabbit, Bird
The eagle takes energy from the rabbit and the bird.Rabbit and Bird >> Eagle

A family took their newborn to the doctor. They were worried something was wrong because the baby seemed to be in constant pain. After medical tests revealed the baby had large amounts of lactic acid accumulating in his muscle cells, doctors diagnosed the child with a rare disease in which mitochondria are missing from skeletal muscle cells. How might the lack of mitochondria explain the large amounts of lactic acid in the baby's muscle cells
Mitochondria help in the complete metabolism of sugar to produce energy in the cell (ATP). Mitochondria is the powerhouse of the cell.
Glycolysis is the first step in the metabolism of glucose. By the process of glycolysis, glucose is converted to pyruvate with the generation of ATP and NADH. The pyruvate is then converted to acetyl CoA by the pyruvate dehydrogenase complex which then enters the TCA cycle. The NADH FADH2 generated by Glycolysis and TCA cycle donate their electrons to the electron transport chain which in turn helps in the generation of ATP. Both the TCA cycle and the Electron transport chain take place within the mitochondria. In the absence of mitochondria, NAD+ and FAD are regenerated by fermentation.
In the process of converting 3-carbon pyruvate to 3-carbon lactic acid (C3H6O3), lactic acid fermentation also regenerates NAD+, which enables glycolysis to continue producing ATP in the absence of mitochondria. This leads to the accumulation of lactic acid in muscle cells.

Find the element in the periodic table. Find out the period (rows) it is in, and draw that number of circles.
Answer:
Name of element: Oxygen (O)
Period (Row): 2
The number of the period (row) in which the element is in tells us how many energy levels (known as shells or circles) the element has.
Because Oxygen is in row 2 it tells us we need to draw 2 circles.
The group that the element is in also tells us the number of electrons present in the element's outer energy level (also known as an outer shell or outer circle).
Because Oxygen is in group 6 it must have six electrons on its outer energy level.
We know that the first energy level always has two electrons.
So we draw two energy levels. On the first energy level, we draw 2 dots or crosses (to represent the two electrons). On the second energy level, we draw 6 dots or crosses.

2. Which characteristic do most cartilaginous fish have?
1 ; swim bladder
2:spiracles
3:external fertilization
Answer:
Option 2: Spiracles.
Explanation:
Cartilaginous fish (also called Chrondricytes) have a skeleton of cartilage, instead of bone. There are two subclasses - Elasmobranchii and Holocephali. Sharks, rays, skates and sawfish are elasmobranchs while chimeras are holocephali.
Here’s a list of features of cartilaginous fish in comparison to bony fish:
1. Cartilage skeleton: unlike bony fish that have a skeleton made of bones (just like other terrestrial vertebrates), the skeleton of cartilaginous fish is made of cartilage.
2. Spiracles: this is a modified gill of sorts, it aids with respiration and is found slightly behind each eye. It leads directly to the mouth. Most cartilaginous fish possess this organ (exceptions are present, such as hammerhead sharks). Bony fish do not possess spiracles.
3. Ampullae of Lorenzini: absent in bony fish, these organs are electroreceptors that form a network of pores filled with a form of jelly that can transmit electrical signals. It allows the cartilaginous fish to sense electric fields in the water (such as the movements of a fish struggling), magnetic fields and temperature. Some bony fish such as sturgeon and lungfish may possess these organs, however research is still ongoing.
4. Claspers: male cartilaginous fish possess an organ known as claspers at their pelvic fin. This is used during reproduction to transfer the sperm into the female for fertilisation. As such, internal fertilisation occurs in cartilagonous fish. Bony fish do not possess this organ, and external fertilisation occurs.
There are many other characteristics that differentiate cartilaginous fish from bony fish. They're an extremely fascinating group of animals that unfortunately, is decreasing in numbers. Very little is known about many of these animals, so it is important that we do our best to conserve the sharks, rays, sawfish and chimeras before we lose them forever.
As the DNA is unwound to allow replication, torsion builds up which would prevent further movement of the replication fork. What general class of enzyme allows DNA to assume a more relaxed state
Topoisomerase enzyme allows DNA to assume a more relaxed state.
DNA topoisomerases (or topoisomerases) are enzymes that catalyze changes in the topological state of DNA, interconverting relaxed and supercoiled forms, linked (catenated) and unlinked species, and knotted and unknotted DNA. This enzyme prevents the DNA double helix in front of the replication fork from winding up too tightly as the DNA unwinds
