During synthesis of triacylglycerols from free fatty acids Acetyl-CoA is least important in this synthesis.
Acetyl-CoA would not be important because thats what that product is based from the synthesis,
The biosynthesis of triacylglycerol occurs in the endoplasmic reticulum (ER) and involves acyl-editing of fatty acyl chains within the nitrogenous phospholipids of the ER.
The enzyme glycerol kinase has no role to play in the synthesis of triacylglycerol.
Pancreatic enzymes called lipases then hydrolyze the dispersed fats to give monoglycerides and free fatty acids. These products are absorbed into the cells lining the small intestine, where they are resynthesized into triglycerides.

What is the primary advantage of noneugenol periodontal surgical dressing over periodontal surgical dressing that does contain eugenol?
Some people may develop redness and burning discomfort in the vicinity of the bandage if they are allergic to eugenol.
In order to lower the danger of surgery site infection and bleeding, speed up wound healing, and lessen patients' pain and discomfort, periodontal dressings were devised.The ability of eugenol-based dressings to numb pain and make sites less sensitive made them popular in the past, especially after gingivectomy. Based on its antibacterial qualities, zinc oxide-eugenol dressings appeared to prevent or delay bacterial development. However, it was discovered that eugenol irritated oral mucosal tissues, caused allergic reactions, and caused tissue necrosis, especially in bone, which slowed the healing process. Thus, noneugenol periodontal surgical dressing are preferred.learn more about eugenol here: https://brainly.com/question/17092785

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.

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.

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.

The cell cycle involves the different stages which a cell goes through as it grows and divides in order to form new cells. Cell cycle requires metabolic energy as well as the availability of nutrients. In eukaryotes, this cycle is basically divided into interphase and mitosis.
The interphase can be subdivided into G1, S and G2 phases. The cell spends most of its time in this stage. It involves the duplication of the nuclear DNA which is present in the cell and during this stage the cell grows in size. No division of the cell takes place during interphase. This stage is succeeded by mitosis. This stage involves the division of the cell, that is, the single eukaryotic cell divides and results in the formation of two daughter cells which are genetically identical to their parent cell.

Polygenic heritability is the expression of a trait by many genes interaction. 1) 180mm. 2) 15/64
What is polygenic heritability?
Polygenic heritability occurs when a trait results from the interaction of many genes.
Individuals are grouped in categories that depend on how genes were intercrossed and distributed during meiosis.
In this example, there are three diallelic genes. We know that
all alleles add the same length to the leaves, the largest leaves are the homozygous dominant ones (AAWWLL⇒ 220mm), the shortest leaves are the homozygous recessive ones (aawwll⇒ 100mm).By looking at the difference between lengths (220 - 100 = 120mm), we might say each dominant allele adds 20 mm to the leaves (120mm/6alleles = 20mm).
Plants llWWHH have 4 dominant alleles, meaning their leaves' length is 180 mm.
Among the F2, 15/64 individuals are expected to have 180 mm leaves.

Seeds of sun-loving plants will germinate and grow in it.
Gap dynamics in forestsForests generally have different layers of trees. Thus, the ground layer of forests is usually barren or dominated by a few shade-tolerant plant species.
When gaps emerge in an otherwise close canopy either naturally or by other means, the dynamics of plant population on the ground layer change.
If the ground layer is barren before due to shade, propagules of sun-loving plant species will colonize and begin to germinate in the gaps. If the layer has some shade-tolerant herbs before, competition for space starts between the sun-loving and shade-tolerant species.
