Energy Considerations: Catabolic and Anabolic Processes

00:01 A well oiled machine has hundreds of parts all working together in a unison to accomplish the functions of a machine.

00:08 For a cell ideally metabolic control is working like a well oiled machine and that's the focus of this presentation.

00:16 In this talk, I will discuss energy considerations relative to cellular needs, futile cycles, reciprocal regulation, the cori cycle, and finally, hormonal control, how everything integrates together.

00:31 Now cells have needs for energy. There are times when they need to make ATP and there are times when they have plenty of ATP.

00:38 Catabolic processes which are the break down processes, generate energy for cells and they harvest that energy in the form of ATP.

00:47 Catabolic processes are ideally active in circumstances of low energy and inactive in circumstances of high energy, so as not to waste that energy.

00:56 Anabolic processes are the opposite.

00:58 They require input of energy and so it’s ideal if they are active when the high energy state of the cell exists such as when there is plenty of ATP.

01:06 And they are inactive in circumstances of low energy when there is, of course, low ATP.
