At the neuromuscular junction, an electrical signal from the motor neuron is translated to a chemical signal and then back to an electrical signal in the muscle cell. What proteins interact with the released chemical to cause the electrical signal in the muscle cell?.
Cation ligand-gated channels are the proteins that interact with the released chemical to cause the electrical signal in the muscle cell.
Neurotransmitters are chemical signals released in the cleft when a nerve impulse arrives at the neuromuscular junction. A ligand-gated cation channel opens as a result of these chemical signals binding to the motor endplate's receptor. The receptor contains these channels. Cations, specifically Na+, can flow across the membrane by opening ion channels. A muscle action potential is sparked by the introduction of cations, which increases the positive charge of the muscle fiber's interior. acetylcholine is found in motor neuron synaptic vesicles at a neuromuscular junction.

what waste product do yeast produce under anaerobic conditions? what waste product do yeast produce under anaerobic conditions? lactic acid ethyl alcohol pyruvic acid creatine
Yeast produces carbon dioxide and ethyl alcohol when it is anaerobic.
They do this through a process known as fermentation in which glucose molecules are consumed. Because the carbon dioxide produced during the baking process aids in the bread's rising, yeast is added.
What about anaerobic conditions?When the intake or loss of oxygen exceeds that of its production through photosynthesis or diffusion by physical transfer from the surrounding environment, anaerobic conditions are present. Due to the availability of organic material, microbial respiration typically consumes oxygen. A set of metabolic processes allow cells to regenerate their energy under anaerobic conditions. Fermentation is the name given to this process. The Krebs cycle is stopped when there is an anaerobic environment. Clostridium botulinum and the microorganisms that dwell close to hydrothermal vents on the deep-sea ocean floor are two examples of obligate anaerobes. Organisms that can tolerate the presence of oxygen but cannot use it for growth. Anaerobes that can develop in the absence of oxygen yet use it when it is available. When referring to plants, the terms "hypoxic" or "anaerobic conditions". When there is little to no oxygen available in the substrate or soil. Water replaces the oxygen that was present in the soil profile's pores. The microbial, fungal, and plant activities quickly deplete any remaining oxygen when saturated conditions persist.Learn more about anaerobic conditions here:

the folowing statements are true about fermentation: a. all of the above are true b. net two molecules of atp are produced c. takes place in prokaryotes and eukaryotes. d. does not require o2.
All of the above statements are true about fermentation. In fermentation, net two molecules of ATP are produced. This process takes place in both prokaryotes and eukaryotes. However, fermentation does not require oxygen.It is an anaerobic process.
Fermentation is a metabolic process that produces ATP through the breakdown of glucose. This process does not require oxygen and takes place in the absence of oxygen. In fermentation, glucose is converted into pyruvate, and then pyruvate is converted into ATP. The net production of two ATP molecules per glucose molecule is lower than that of aerobic respiration, but fermentation does not require oxygen, making it an important process in anaerobic conditions.
Fermentation is used by many organisms, including bacteria, yeast, and some plants. In bacteria, fermentation is used to produce lactic acid, which is then converted into ATP. In yeast, fermentation is used to produce ethanol and carbon dioxide. In plants, fermentation is used to produce lactic acid, ethanol, and carbon dioxide.
Fermentation is an important process in the food industry. It is used to produce bread, wine, beer, and cheese. It is also used to produce yogurt, sauerkraut, and other fermented foods.

What differences in structure would be necessary in order for each limb to accomplish its specific functions
Cells must be specified and committed to make the limbs. For a limb to be formed, the specific muscle cells for the limbs should be formed. The limbs of different animals vary.
What is cell specification?Cell specification is a phenomenon in which the cell is committed to a certain function and can't change it. In the zygote stage, the cell is not committed to any particular function, but as the cells multiply, they begin to commit to a particular cell type. Cells such as the muscle cells of the limb should be specified and committed to the particular structure that is required for the limb. The minimum structures for the limb are structures to move, to make living place by digging the soil etc. so the limb should have nails, claws , digits etc.
Hence, because no specific animal limb is mentioned, cell specification and commitment are the result of the limb's specific structural features.

what is one way the vision of primates is different from that of other animals? group of answer choices
One way in which primates have a different way of vision than other animals is that primates have overlapping vision fields.
Compared with many other animals, primates have more closely spaced, forward-facing eyes that allow for a lot of overlap between each eye's visual field, which in turn gives primates 3-D, or stereoscopic, vision and a good sense of depth perception.
This gives a wider field of view. For example, humans have a maximum horizontal field of view of approximately 190 degrees with two eyes, approximately 120 degrees of which makes up the binocular field of view (seen by both eyes). It also allows a creature with this type of vision to see more of, or all of, an object behind an obstacle.

Endocytosis is the process by which a virus is taken up by a host cell as a result of the host cell's cytoplasmic membrane surrounding the virion to form a vesicle.
Endocytic machinery, a sophisticated collection of vesicles and proteins, has been developed by cells to ingest substances. In response, certain viruses have learned how to manipulate the cell's endocytic machinery in order to access the cytoplasm or nucleus of the host cell, depending on the virus's chosen method of replication.
Step-by-step processes for endocytic entry of viruses include an attachment to the cell surface, receptor clustering, signaling pathway activation, production of endocytic vesicles and vacuoles, transport of viral payload to endosomal compartments, sorting, as well as escape into the cytosol.
For a virus to begin replicating, its genome must enter the host cells. Most viruses enter cells by endocytosis, while others can directly pierce the plasma membrane and inject their genetic material into the cytoplasm.

A lichen's basic structure is made up of layers of fungus and algae.Lichens do not have vascular tissue like xylem and phloem to carry nutrients and water throughout their thalli like a plant does, nor do they have a waxy coating like plants do on their leaves. The structure of the lichen incorporates everything in its surroundings. Lichens obtain their water and nutrients from the air and rain that fall on them.What is the symbiotic association between algae and fungi?
Symbiotic association means two or more distinct organisms living together for the benefit of one or both.
Fungi lack chlorophyll, which is a green pigment necessary for photosynthesis. Fungi are unable to produce carbohydrates on their own and obtain light energy from the sun. Instead, they must look for other food sources. They take in organic foods, or chemicals containing carbon like proteins, lipids, or carbs.Algae and cyanobacteria, on the other hand, can carry out photosynthesis similarly to plants.
