The Krebs cycle, also known as the Citric Acid cycle, is a very important process in cellular respiration. Without this portion, respiration would not be possible. This is because the Krebs cycle uses the pyruvate molecules from glycolysis to produce...

Catabolic and Anabolic
What exactly are Catabolic and Anabolic reactions?
Catabolic and anabolic reactions are both metabolic processes that go to support an organisms metabolism.
Catabolic reactions make energy for the cell to use by breaking down large molecules and turning them into energy called ATP, or Adenosine Triphosphate. An example of a Catabolic reaction would be digestion. When an organism digests its food, it breaks it down and collects the energy from it and then sends the energy on to be used in the organism itself.
Once ATP is produced, Anabolic reactions use it to make molecules that the cell needs to keep working and stores the left over molecules for later. An example of an Anabolic reaction would be when an organisms body creates fat out of extra nutrients it it digests.
A Catabolic reaction and an Anabolic reaction do the opposite of what the other does, but one could not survive without the other. Catabolic reactions break down large molecules into small ones while Anabolic reactions build small molecules into large ones. So in a way, one makes an organism grow and the other makes it shrink. If they work at the same speed then an organism can stay healthy and fit and not be malnourished. If the two reactions do not work at the same speed an organism can become over weight or underweight and either lead into even more issues with the organisms health.
Why do organisms need both? So that the organism can transfer energy from one area and place it into another where the organism can either use or store it.
