Front

What is ADP?

Back

ADP is the molecule that ATP becomes when it gives up one of its three phosphate groups.

Front

What is ATP?

Back

ATP is the main energy source that cells use for most of their work.

Front

What is ATP composed of?

Back

ATP is composed of adenine, ribose, and a phosphate group.

Front

What does it mean to denature a protein?

Back

Denaturing a protein refers to a change in shape that stops the protein from functioning.

Front

What is a spontaneous reaction?

Back

A spontaneous reaction is one that doesn't require energy to proceed, although it doesn't mean it will be fast.

Front

What is the role of ATP in cellular processes?

Back

ATP provides energy for various cellular processes, including muscle contraction, nerve impulse propagation, and biosynthesis.

Front

What is the structure of ATP?

Back

ATP consists of an adenine base, a ribose sugar, and three phosphate groups.

Front

What happens to ATP during cellular respiration?

Back

During cellular respiration, ATP is produced from ADP and inorganic phosphate through processes like glycolysis and the citric acid cycle.

Front

What is the significance of the phosphate groups in ATP?

Back

The phosphate groups in ATP store potential energy, which is released when they are hydrolyzed.

Front

What is competitive inhibition?

Back

Competitive inhibition occurs when a substance competes with the substrate for binding to the active site of an enzyme.
