Termini in questo set(13)
What does ATP stand for?
ATP stands for adenosine triphosphate.
Function of ATP?
ATP provides energy for cellular activities by releasing a phosphate group.
True or false: ATP is the energy currency of the cell.
True, because it is used to fuel various cellular processes.
Difference between ATP and ADP?
ATP has three phosphate groups, while ADP has two. ATP is energy-rich, whereas ADP is energy-poor.
Fill in the blank: ATP is produced during _____.
cellular respiration and photosynthesis.
What is the structure of ATP?
ATP consists of adenosine (adenine + ribose) and three phosphate groups.
How is energy released from ATP?
Energy is released when the terminal phosphate group is hydrolyzed.
Question: What happens to ATP during muscle contraction?
ATP is hydrolyzed to ADP, providing energy for the contraction.
True or false: ATP can be recycled.
True, because ADP can be converted back to ATP through phosphorylation.
What is phosphorylation?
Phosphorylation is the addition of a phosphate group to a molecule, often to convert ADP to ATP.
Key process that regenerates ATP?
Cellular respiration regenerates ATP through glycolysis, the Krebs cycle, and oxidative phosphorylation.
How does ATP relate to enzymes?
ATP often serves as a substrate for enzymes, facilitating biochemical reactions.
Fill in the blank: ATP is essential for _____ transport across membranes.
active transport
