Metabolic regulation . always involves changing the amount of an enzyme in the cell b. is the same thing as metabolic control c. maintains all reactions in a pathway near the equilibrium of each d. is the maintenance of homeostasis at a molecular level

Answer:

Metabolic regulation D: Is the maintenance of homeostasis at a molecular level

Explanation:

Homeostasis means resistance to change to maintain a stable and constant internal environment in organisms. Body maintains homeostasis for many reasons like to maintain temperature, controlling pH and glucose levels. If these levels fluctuate, person can get sick.

Metabolic regulation provides an ideal homeostasis mechanism. It is a process by which body takes in nutrients in the form of food and energy is being delivered to us. Metabolic regulation includes regulation of an enzyme in a route of the body by responding either less or more to signals.

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
