happened to the majority of the energy that
was in the original glucose molecule?
a. it is stored in nadh and fadh2.
b. it is stored in adenosine diphosphate.
c. it is stored in adenosine dioxide.

1. where in the cell does glycolysis take

place?
a. mitochondrion
b. chloroplast
c. cytoplasm
d. vacuole

1. what organelle would be represented by

this diagram?
a. mitochondria
b. nucleus
c. chloroplast

1. the cell membrane contains channels

and pumps that help move materials
from one side to the other. what are
these channels and pumps made of?
a. carbohydrates
b. lipids
c. bilipids
d. proteins

1. the diffusion of water across a

selectively permeable membrane is
called
a. osmotic pressure.

Explanation:

1. Glucose is the starting molecule for glycolysis.
2. Muscle soreness is due to lactic - acid fermentation.
3. Breathing heavily after running is the body's way of repaying an oxygen debt.
4. NAD+ release occurs in glycolysis.
5. Photosynthesis occurs in chloroplasts.
6. Aerobic cellular respiration takes place in mitochondria.
7. With oxygen present, cellular respiration yields 38 ATP per glucose molecule.
8. Adenosine Triphosphate (ATP) is a nucleic - acid macromolecule.
9. ATP releases energy by breaking the bond between the second and third phosphate groups.
10. Glycolysis takes place in the cytoplasm.
11. The diagram represents mitochondria as it is related to energy production (ATP).
12. The channels and pumps in the cell membrane are made of proteins.
13. The diffusion of water across a selectively permeable membrane is called osmosis.

Answer:

1. Glucose
