<u>Answer</u>:
Metabolic regulation D: Is the maintenance of homeostasis at a molecular level
<u>Explanation</u>:
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 Golgi apparatus is responsible for packing proteins from the rough endoplasmic reticulum into membrane-bound vesicles which then trans locate to the cell membrane. At the cell membrane, the vesicles can fuse with the larger lipid bi layer, causing the vesicle contents to either become part of the cell membrane or be released to the outside.
This process is known as D. plasmolysis
Plasmolysis occurs when a cell is placed in a hypertonic solution. The osmotic potential is higher within the cell than in the surrounding solution, which results in water moving out of the cell. This causes reduction in volume of the cells, but plant cells tend to retain their outer shape due to their rigid cell walls.
