This organelle is the site of photosynthesis in plant cells.

What is the chloroplast?

100

This process breaks down glucose to release usable energy for the cell.


What is cellular respiration?

100

This molecule is the cell's main immediate energy carrier.

What is ATP?


100

This green pigment absorbs light energy in plants.

What is the chlorophyll?

100

This stage of cellular respiration occurs in the cytoplasm, not in the mitochondria.

What is glycolysis?

200

These two substances are the main reactants of photosynthesis.

What are carbon dioxide and water?

200

These are the two main reactants of aerobic cellular respiration.

What are glucose and oxygen?

200

ATP provides this to power processes that require energy inside the cell.


What is chemical energy?

200

These flattened membrane sacs are found inside chloroplasts.

What are thylakoids?

200

After glycolysis, pyruvate enters the mitochondrion and is prepared for this cycle, which occurs in the mitochondrial matrix.


What is the Krebs cycle?

300

What type of energy is converted into chemical energy during photosynthesis?

What is light energy?

300

These are the major products of aerobic cellular respiration.

What are carbon dioxide, water, and ATP?

300

During glycolysis, one molecule of glucose is broken down into two molecules of this three-carbon molecule.

What is pyruvate?

300

This fluid-filled region surrounds the thylakoids and is where the Calvin cycle occurs.

What is the stroma?

300

The stage of cellular respiration that requires oxygen.

What is the electron transport chain?

400

The carbon atoms found in the glucose produced by photosynthesis originally come from this molecule.


What is carbon dioxide?

400

This is the first stage of cellular respiration and occurs in the cytoplasm.

What is glycolysis?

400

These electron carriers transport high-energy electrons from glycolysis and the Krebs cycle to the electron transport chain.

What are NADH and FADH₂?

400

A plant is producing oxygen even though it is not taking oxygen in from the air. Which molecule is being split to provide the oxygen released during photosynthesis?

What is water?

400

A student says that glycolysis should happen inside the mitochondrion because all cellular respiration happens there. What is wrong with the student's reasoning?

What is glycolysis occurs in the cytoplasm, while the Krebs cycle and later stages of aerobic respiration occur in the mitochondria?

500

A plant has plenty of water and carbon dioxide but is kept in complete darkness. Predict what will happen to its production of glucose and explain why.


What is glucose production will decrease or stop because light energy is required for photosynthesis?

500

A muscle cell does not have enough oxygen available during intense exercise. Which alternative process can allow glycolysis to continue?


What is lactic acid fermentation?

500

Put these stages of aerobic cellular respiration in the correct order: electron transport chain, glycolysis, Krebs cycle.

What is glycolysis → Krebs cycle → electron transport chain?

500

A scientist damages the thylakoid membranes of a plant cell. Which part of photosynthesis would be most directly affected?


What are the light-dependent reactions?

500

A muscle cell contains many more mitochondria than a typical skin cell. Why might this difference be beneficial to the muscle cell?

What is muscle cells require large amounts of ATP for contraction, so having more mitochondria allows them to produce more usable energy through aerobic cellular respiration?
