Want this question answered?
When the cell has too much ATP the process of making ATP slows down: this leads to fatty-acid synthesis (fat storage).
No, of course !
It does not require glucose directly. In cellular respiration any molecule that is within the pathway and is available can be used in cellular respiration. But in lamen explanation glucose is the most popular example used in the beginning of the aerobic repiration pathway.
Yes
Perhaps you don't understand the meaning of positive and negative feedback. Positive feedback keeps adding to a process. Negative feedback doesn't. If a person fills a bathtub, positive feedback will continue the filling even if it runs over. Negative feedback will turn the water off when the tub is filled. So, negative feedback maintains homeostasis. Homeostasis means "steady state". When a processes is completed, it turns it off. Example: Blood sugar levels remain in a certain range.
I Have Noo Clue
Is the clotting of blood an example of positive or negative feedback?

Positive feedback in economic systems can cause boom-then-bust cycles. A familiar example of positive feedback is the loud squealing or howling sound.
Postive feedback
Aerobic Reaction. Respiration is an example of aerobic reaction, and is common to living organisms such as humans and plants. Anaerobic respiration can be found in certain types of bacteria.

A positive feedback mechanism is a system the responds to perturbation in the same direction as the perturbation. A positive feedback mechanism allow cells to adapt to changes in their environment rapidly and efficiently. Positive feedback allows cells to reach new levels of equilibrium corresponding to the stimulus in the environment
