Cellular Energy Biology EOC Review Questions

Front

What is the purpose of an enzyme?

Back

Enzymes speed up reactions by lowering the activation energy required.

Front

What is the optimum pH of the enzyme based on the graph?

Back

The optimum pH of the enzyme is 6.6.

Front

What is the optimal temperature for this enzyme?

Back

The optimal temperature for this enzyme is 30°C.

Front

What gases are used and released in photosynthesis and cellular respiration?

Back

Cellular respiration uses oxygen and releases carbon dioxide, while photosynthesis uses carbon dioxide and releases oxygen.

Front

What is activation energy?

Back

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

Front

Define photosynthesis.

Back

Photosynthesis is the process by which green plants use sunlight to synthesize foods with the help of chlorophyll.

Front

Define cellular respiration.

Back

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

Front

What role do enzymes play in metabolic reactions?

Back

Enzymes act as catalysts to speed up metabolic reactions without being consumed in the process.

Front

What is the relationship between enzyme activity and temperature?

Back

Enzyme activity typically increases with temperature up to a certain point, after which it decreases due to denaturation.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily from the sun, to drive the photosynthesis process.
