ATP
Definition
ATP (adenosine triphosphate) is the primary energy carrier in all living organisms. It stores and transfers energy within cells for various metabolic processes.
5 Must Know Facts For Your Next Test
- ATP is produced during glycolysis, which occurs in the cytoplasm of the cell.
- One molecule of glucose can generate a net gain of 2 ATP molecules through glycolysis.
- ATP consists of adenine, ribose (a sugar), and three phosphate groups.
- The hydrolysis of ATP to ADP (adenosine diphosphate) releases energy that cells use for biological work.
- Enzymes like hexokinase and phosphofructokinase regulate key steps in glycolysis where ATP is both consumed and produced.
Review Questions
- What are the components that make up an ATP molecule?
- How many net ATP molecules are produced from one molecule of glucose during glycolysis?
