What happens in the Calvin cycle of photosynthesis?

1. AIn the stroma
2. BIn the outer membrane
3. CIn the cell wall
4. DIn the thylakoid membranes

Why do chromosomes condense into short, thick shapes before mitosis?

1. ASo that genes can be transcribed more easily
2. BSo that they can be copied more quickly
3. CSo that they can leave through the nuclear pores

Why do cells get far more ATP from glucose when oxygen is present than when it is absent?

1. AWithout oxygen the Krebs cycle runs faster but makes less ATP
2. BOxygen itself is converted into ATP in the mitochondria
3. CWithout oxygen only glycolysis runs, giving a net of 2 ATP per glucose
4. DWithout oxygen, glucose cannot enter the cell or be broken down at all
