100
This gas is taken in by plants during photosynthesis.
What is carbon dioxide (CO₂)?
100
What are the two main inputs of cellular respiration?
What are glucose and oxygen?
100
Proteins that speed up chemical reactions are called ____.
What are enzymes?
100
Controls what enters and leaves the cell.
What is the cell membrane?
100
The phase where the cell grows and DNA replicates.
What is interphase?
200
Photosynthesis requires this molecule from the soil as an input.
What is water (H₂O)?
200
This gas is released as a waste product during cellular respiration.
What is carbon dioxide (CO₂)?
200
The place where the substrate binds on an enzyme.
What is the active site?
200
This organelle converts sugar into ATP.
What is the mitochondrion?
200
In this phase, chromosomes line up across the middle of the cell.
What is metaphase?
300
What are the two main products of photosynthesis?
What is glucose and oxygen?
300
Name all three outputs of cellular respiration.
What are carbon dioxide, water, and ATP (energy)?
300
Describe the “lock and key” model.
enzymes fit only one substrate based on shape
300
What structure provides support and protection in plant cells but not animal cells?
What is the cell wall?
300
Spindle fibers pull sister chromatids apart in this phase.
What is anaphase?
400
Which set of reactions releases oxygen as a product?
What are the light-dependent reactions?
400
Which stage of cellular respiration makes the most ATP?
What is the electron transport chain?
400
Name two conditions that can denature enzymes.
What are high temperature and extreme pH?
400
Match the structure to its function:
– Rough ER
– Smooth ER
Rough ER makes proteins; Smooth ER makes lipids and detoxifies.
400
Describe what happens during telophase.
What is nuclei reform, chromosomes uncoil, and spindle fibers disappear?
500
Explain how the inputs and outputs of photosynthesis and cellular respiration show that the two processes are complementary.
Photosynthesis makes glucose and oxygen — the inputs for cellular respiration — and cellular respiration produces CO₂ and H₂O, which are the inputs for photosynthesis.
500
Draw how a catalyst changes the activation energy of a reaction.

A cell shows a large vacuole, chloroplasts, and a rigid outer boundary. Identify the type of cell and explain your reasoning.
What is a plant cell? It has chloroplasts, a central vacuole, and a cell wall.
500
Explain the difference between mitosis and cytokinesis.
What is mitosis divides the nucleus while cytokinesis divides the cytoplasm, producing two identical daughter cells?
