Answer;
-Glycogen
The organic molecule called glycogen is formed of branched chains of sugar units.
Explanation;
-Glycogen is a branched polysaccharide of glucose that serves as a form of energy storage in humans, animals, fungi, and bacteria.
-In humans, glycogen is made and stored in liver and muscle cells. Muscle cell glycogen is broken down into glucose, and liver glycogen is broken down into glucose as a circulating energy source glucose for use by the body.
-Glycogen is accumulated in response to insulin and broken down into glucose in response to glucagon. It plays a major role in maintaining the blood-glucose levels, which is vital since some organs in the body such as the brain purely depend on glucose for energy.
I BELIEVE the answer is D) 4.
A. If the optimum temperature for a cell's functions is exceeded, chemical reactions slow down as enzymes and other proteins begin to denature (change shape due to increased vibration of the atoms in the molecules that make up the proteins).
It is not a mineral because it is man made!
