What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes are biological catalysts that speed up chemical reactions in cells by lowering the activation energy required for the reaction.

Front

What is the optimum pH for enzyme activity?

Back

The optimum pH is the pH at which an enzyme's activity is at its maximum. For many enzymes, this is around neutral pH (6-8), but it can vary.

Front

What is photolysis?

Back

Photolysis is the process of using light energy to split molecules, such as water, during the light-dependent reactions of photosynthesis.

Front

What are substrates in enzyme reactions?

Back

Substrates are the reactants that enzymes act upon in a biochemical reaction.

Front

What is the active site of an enzyme?

Back

The active site is the specific region of an enzyme where the substrate binds and the reaction occurs.

Front

What is the difference between light-dependent and light-independent reactions?

Back

Light-dependent reactions require sunlight to produce ATP and NADPH, while light-independent reactions (Calvin cycle) use these products to synthesize glucose.

Front

What is the significance of the enzyme suffix '-ase'?

Back

The suffix '-ase' is commonly used to denote enzymes, indicating their role in catalyzing biochemical reactions.

Front

What is the Calvin cycle?

Back

The Calvin cycle is a series of biochemical reactions that occur in the stroma of chloroplasts, where carbon dioxide is fixed into glucose using ATP and NADPH.
