Front

What is the role of enzymes in chemical reactions?

Back

Enzymes speed up chemical reactions by decreasing the activation energy required for the reaction to occur.

Front

How does substrate binding affect enzyme activity?

Back

Substrate binding activates the enzyme by changing its shape, which facilitates the chemical reaction.

Front

What is the primary enzyme involved in carbon fixation during photosynthesis?

Back

Rubisco is the primary enzyme used for carbon fixation.

Front

Where did the process of photosynthesis first originate?

Back

Photosynthesis originated in cyanobacteria.

Front

Which phase of photosynthesis converts solar energy into ATP?

Back

The Light Reactions store solar energy as ATP.

Front

Define activation energy in the context of chemical reactions.

Back

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

Front

What is the Calvin Cycle?

Back

The Calvin Cycle is a series of biochemical reactions that take place in the stroma of chloroplasts during photosynthesis, where carbon dioxide is converted into glucose.

Front

Explain the difference between the Light Reactions and the Calvin Cycle.

Back

The Light Reactions capture solar energy and convert it into ATP and NADPH, while the Calvin Cycle uses these products to synthesize glucose from carbon dioxide.

Front

What is the function of ATP Synthase in photosynthesis?

Back

ATP Synthase is an enzyme that synthesizes ATP from ADP and inorganic phosphate during the Light Reactions.

Front

What are accessory molecules in enzyme activity?

Back

Accessory molecules, such as cofactors and coenzymes, assist enzymes in catalyzing reactions.
