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.
Creep is a solid material's tendency to deform permanently under pressure or stress.
So, a cracked telephone pole or a broken sidewalk would be examples.
fats are composed of high amounts of saturated fatty acids which are solid at room temperature and oils are composed of mainly unsaturated fatty acids which are a liquid at room temperature
