Unit 3 Concept 1 and 2 (Enzymes and ATP)

Front

What are the components of an ADP molecule?

Back

An ADP (Adenosine Diphosphate) molecule consists of an adenine base, a ribose sugar, and two phosphate groups.

Front

What happens to ATP when it releases energy?

Back

ATP releases energy when it loses a phosphate group, converting into ADP.

Front

Define endothermic reactions.

Back

Endothermic reactions are chemical reactions that absorb more energy than they release.

Front

How does temperature affect reaction rates?

Back

An increase in temperature generally results in an increase in reaction rate.

Front

What is the primary function of ATP?

Back

The primary function of ATP is to store energy for cellular processes.

Front

What is the difference between exothermic and endothermic reactions?

Back

Exothermic reactions release energy, while endothermic reactions absorb energy.

Front

What is activation energy?

Back

Activation energy is the minimum energy required for a chemical reaction to occur.

Front

How do enzymes affect chemical reactions?

Back

Enzymes act as catalysts, lowering the activation energy required for reactions and increasing reaction rates.

Front

What is the role of ATP in metabolism?

Back

ATP serves as the energy currency of the cell, providing energy for various metabolic processes.

Front

What is a catalyst?

Back

A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.
