Card preview (9)
What is ATP?
Adenosine triphosphate — the universal energy currency of the cell. Keywords: ATP, nucleotide, energy carrier.
What are the components of ATP?
Adenine + ribose = adenosine, plus three phosphate groups. Keywords: adenosine, triphosphate.
How does ATP release energy?
Hydrolysis → ATP → ADP + Pi, releasing ~30.7 kJ/mol. Energy comes from bond formation in products. Keywords: hydrolysis, ATPase, ADP, Pi.
Why is ATP instantly usable?
It releases energy in small, manageable quantities and is rapidly regenerated. Keywords: immediate energy, rapid turnover
Describe ATP–ADP cycling.
ATP hydrolysis releases energy; ADP is rephosphorylated during cellular respiration. Keywords: phosphorylation, rechargeable battery analogy.
How is ATP used in active transport?
Powers pumps moving substances against concentration gradients. Keywords: ion pumps, active transport.
How is ATP used in biosynthesis?
Fuels anabolic reactions such as DNA replication, protein synthesis. Keywords: anabolic, biosynthesis.
How is ATP used in movement?
Powers motor proteins (dynein, kinesin) in cilia, flagella, muscle contraction. Keywords: motor proteins, movement.
Why do cells need ATP?
To maintain homeostasis, metabolism, and power all energy-requiring processes. Keywords: metabolism, cell processes.
