ATP
Definition
ATP (Adenosine Triphosphate) is the primary energy carrier in cells. It stores and provides energy necessary for various cellular processes.
5 Must Know Facts For Your Next Test
- ATP is produced during cellular respiration, particularly in the mitochondria.
- During catabolism of carbohydrates, ATP is generated through glycolysis and the Krebs cycle.
- In photosynthesis, ATP is synthesized in the light-dependent reactions to provide energy for the Calvin cycle.
- Many antibacterial drugs target bacterial metabolism pathways that produce ATP, inhibiting their growth.
- ATP can be hydrolyzed to ADP (Adenosine Diphosphate) and an inorganic phosphate, releasing energy.
Review Questions
- What are the main pathways through which ATP is produced during carbohydrate catabolism?
- How does ATP function in photosynthesis?
- Why do some antimicrobial drugs target ATP production in bacteria?
