Answer:
C
Explanation:
Tetrodotozin is a sodium channel blocker. that is; it prevents the opening of sodium channels in the neuron needed for depolarization and action potential production.
T<u>he voltage gated sodium channels in the nerves and skeletal muscles are blocked, action potential are not generated from these areas,Therefore potassium channels are permanently open leading to hyper polarization, and since sodium channels can not open, they remain in refractory state, this leads to muscular paralysis leading to impairments of respiratory and cardiac functions.</u>
Specifically the paralysis of the diaphragm muscles, lead to collapse of the lungs, preventing breathing,leading to suffocation and death.
This is an example of competitive inhibition;The introduction of cholinergic acetycholine neurotransmitter reverses the blockage of sodium channels
Glycolysis is the first step of cellular respiration - the process comprised of series of reactions in which energy is extracted from glucose molecules. The process of glycolysis is almost same in all living organisms.
If we quickly overview the process of glycolysis, we see that it is a process of earning ATPs as a return on ATP investment, why?
- 2 ATP molecules are invested during the first or preparatory phase pf glycolysis.
- 2 ATP molecules are formed for each glyceraldehyde 3-phosphate molecule. Therefore, total four ATP molecules are produced.
- Other than ATP, 1 NADH + H+ is also produced for each molecule of glyceraldehyde 3-phosphate.
Therefore,total amount of 2 NADH and 4ATP molecules are produced.
But since, there was an investment of two ATPs during the preparatory phase of glycolysis. Therefore, a total of 4-2=2 ATPs is formed/ So it is like an earning on an investment.
Hope it help!
