17. Which of the following statements are accurate?
Naddik [55]

Answer:

A. Neurotransmitters can act as ligands.

B. Acetylcholine is a neurotransmitter. It can bind to an acetylcholine receptor on the surface of a cell. If this receptor is also a sodium channel, we would call acteylcholine a ligand and its receptor a ligand gated receptor.

Explanation:

Answer:

A. Neurotransmitters can act as ligands.

B. Acetylcholine is a neurotransmitter. It can bind to an acetylcholine receptor on the surface of a cell. If this receptor is also a sodium channel, we would call acteylcholine a ligand and its receptor a ligand gated receptor.

Explanation:

Neurotransmitter are chemicals that transfer signals between neurons and nerve cells. They control some physical and physiologocal activity such as appetite, food.

Acetycoline is an example of neurotransmitter and it is located in the parasympathetic nervous system. Ligand are substance that form complexes with biomolecule. They serve biological purpose with this biomolecule.

This ligand binds to target site. Neurotransmitter act as ligand by binding to receptor in the postsynaptic neuron and acetycoline a type of neurotransmitter can also serve as ligand they bind to acetycoline receptor on cell surface.

How do cells release <br> Energy in the process of cellular respiration
White raven [17]

Answer:

Explanation:

There are two types of respiration:

1. Aerobic respiration  

2. Anaerobic respiration

Aerobic respiration

It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.

Glucose + oxygen → carbon dioxide + water + 38ATP

Anaerobic Respiration

It is the breakdown of glucose molecule in the absence of oxygen and produce small amount of energy. Alcohol or lactic acid and carbon dioxide are also produced as byproducts.  

Glucose→ lactic acid/alcohol + 2ATP + carbon dioxide

This process use respiratory electron transport chain as electron acceptor instead of oxygen. It is mostly occur in prokaryotes. Its main advantage is that it produce energy (ATP) very quickly as compared to aerobic respiration

A student is studying the amino acid sequence of a protein shared by four organisms. The student wants to know which organism is
MariettaO [177]

Answer:

Organism D.

Explanation:

Amino acids are the monomers of proteins and are linked together by the peptide bond. The protein is obtained from the RNA molecules by the process known as translation.

The amino acid sequence of the proteins can also be used to study the evolutionary relationship between the organisms and the closeness of teh organisms with each other. In the question it is give that organisms A and D has least difference ( 1 amino acid sequence difference) and more related with each other.

Thus, the answer is organism D.
