Lamarck represented the hypothesis that an organism can pass on acquired characteristics during its lifetime to its offspring. This theory was rejected, but nowadays discoveries in the field of epigenetics and somatic hypermutation confirmed part of it and highlighted the possible inheritance of behavioral traits acquired by the previous generation.
The question is incomplete as it does not have the options which are:
A) creatine phosphate.
B) glycolysis.
C) substrate phosphorylation.
D) oxidative phosphorylation.
E) de novo synthesis.
Answer:
D) oxidative phosphorylation.
Explanation:
The ATP is the energy molecule which provides energy to every metabolic process in the organism.
The ATP in humans is produced by a process called cellular respiration where the last phase of the process called electron transport chain produces the highest amount of protein. The electron transport chain is also known as the oxidative phosphorylation as the oxygen is gained and electrons are lost during the phase.
Thus, D) oxidative phosphorylation is correct.
Answer:
a) Acetylcholine is degraded by acetylcholinesterase.
Explanation:
After it binds for its receptor on the plasma membrane of the postsynaptic cell, acetylcholine must be removed in order to prevent repeated stimulation. Acetylcholinesterase is enzyme for the inactivation of acetylcholine, present at all cholinergic synapses. This enzyme hydrolyses acetylcholine and breaks it to the acetate and choline. Choline can be reused for the synthesis of the new acetylcholine molecule so it is taken back into the presynaptic cell.
