What is ATP and what are its components?

• ATP consists of glucose, fructose, and two phosphate groups.

• ATP is a nucleotide composed of DNA, ribose, and one phosphate group.

• ATP is a type of protein made of amino acids.

• ATP is adenosine triphosphate, composed of ribose, adenine, and three phosphate groups.

Why is ATP considered the energy currency of the cell?

• ATP is only used for DNA replication.

• ATP is primarily involved in protein synthesis.

• ATP is a waste product of cellular respiration.

• ATP is the energy currency of the cell because it stores and releases energy for cellular processes.

What is the significance of the high-energy bonds in ATP?

• High-energy bonds in ATP provide energy for cellular processes.

• High-energy bonds in ATP store genetic information.

• High-energy bonds in ATP facilitate oxygen transport in cells.

• High-energy bonds in ATP are used for protein synthesis.

How is ATP synthesized in cells?

• ATP synthesis occurs solely in the mitochondria.

• ATP is produced exclusively in the cytoplasm.

• ATP is synthesized only during photosynthesis.

• ATP is synthesized through glycolysis, the Krebs cycle, and oxidative phosphorylation.

What role does ATP synthase play in ATP production?

• ATP synthase synthesizes ATP from ADP and inorganic phosphate using a proton gradient.

• ATP synthase transports protons across the mitochondrial membrane.

• ATP synthase is involved in the electron transport chain without ATP production.

• ATP synthase breaks down ATP into ADP and phosphate.

What are the main life processes that ATP supplies energy for?

• Cell division

• Muscle contraction, active transport, biosynthesis, cellular respiration

• Photosynthesis

• DNA replication

How does ATP facilitate active transport across membranes?

• ATP is a waste product of active transport processes.

• ATP directly transports substances through the membrane without proteins.

• ATP is used to create concentration gradients across membranes.

• ATP facilitates active transport by providing energy for transport proteins to move substances against their concentration gradient.

What is the process of hydrolysis in relation to ATP?

• The process of hydrolysis converts ADP to ATP, storing energy.

• Hydrolysis of ATP involves the addition of a phosphate group to ADP.

• ATP hydrolysis is the process of breaking down glucose for energy.

• The process of hydrolysis in relation to ATP is the conversion of ATP to ADP and Pi, releasing energy.

What are the products of ATP hydrolysis?

• ATP and water

• ADP and inorganic phosphate (Pi)

• AMP and carbon dioxide

• ADP and glucose

How is energy released during the conversion of ATP to ADP?

• Energy is released through the absorption of light during the reaction.

• Energy is released by converting glucose into ATP.

• Energy is released by breaking the high-energy phosphate bond in ATP.

• Energy is released by forming a new phosphate bond in ADP.
