What is the terminal phosphate group of ATP referred to as?
Gamma phosphate
Which cellular process is ATP primarily involved in?
Metabolism
Multiple Choice: Which of the following processes generates ATP? A) Photosynthesis B) Fermentation C) Both A and B
C) Both A and B
What is the main advantage of ATP as an energy carrier?
It can be quickly synthesized and used
True or False: ATP can be used directly in muscle contraction.
True
What is the relationship between ATP and ADP?
ADP is formed when ATP loses one phosphate group.
Fill in the blank: The conversion of ATP to ADP is an example of a ___ reaction.
exergonic
What happens to ATP during cellular respiration?
It is produced from the breakdown of glucose.

Fill in the blank: ATP is essential for ___ transport across cell membranes.
active
What is the fate of ATP in anaerobic conditions?
It is produced through substrate-level phosphorylation.
