Cellular Respiration and Photosynthesis - Regents

Front

What is the energy currency of the cell?

Back

ATP (Adenosine Triphosphate) is the energy currency of the cell, used to store and transfer energy for various cellular processes.

Front

What process occurs in the mitochondria to produce ATP?

Back

Aerobic respiration occurs in the mitochondria, where glucose is broken down in the presence of oxygen to produce ATP.

Front

What role do guard cells play in plants?

Back

Guard cells regulate the opening and closing of stomata, controlling gas exchange and water loss in plants.

Front

What pigment in chloroplasts reflects green light?

Back

Chlorophyll is the pigment in chloroplasts that reflects green light and is essential for photosynthesis.

Front

What is aerobic respiration?

Back

Aerobic respiration is the process that releases chemical energy from sugars and other carbon-based molecules to make ATP when oxygen is present.

Front

What is the primary function of photosynthesis?

Back

Photosynthesis converts light energy into chemical energy stored in glucose, using carbon dioxide and water.

Front

What is the difference between autotrophic and heterotrophic nutrition?

Back

Autotrophic nutrition involves organisms producing their own food (e.g., plants), while heterotrophic nutrition involves organisms obtaining food from other sources (e.g., animals).

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin Cycle).

Front

What is the role of the electron transport chain in cellular respiration?

Back

The electron transport chain is a series of proteins in the inner mitochondrial membrane that transfer electrons and pump protons to generate ATP.

Front

What is the significance of the Calvin Cycle?

Back

The Calvin Cycle is the light-independent stage of photosynthesis where carbon dioxide is fixed into glucose using ATP and NADPH.
