Answer:
The answer is C multicellular, eukaryotic, heterotrophic
Answer: feed-back
When the product of a metabolic pathway accumulates, it may be able to slow down or turn off the pathway by inhibiting the activity of an enzyme that catalyzes an early step in the pathway. This is referred to as feed-back inhibition.
Explanation:
Feed-back inhibition is said to occur when the final product of a biochemical pathway signal the inactivation of the starting materials of the pathway.
For example: when pyruvate signal the inactivation of phosphofructokinase, the glycolytic pathway gets turned off.
Answer:
b. 100nm
Explanation:
The correct answer to the given question is 100nm. Low level of oxygen is observed when active fibers are at a distance of 50m or more than 50m from the perfused capillary, this is why the correct answer to the given question is 100nm, which is the option b. in the given question.
