To convert the energy of glucose into the usable form of ATP is a function of _________.

• Cell Wall

• Cytoplasm

• Nucleus

• Mitochondria

Multiple Choice

Why are cristae important for the function of the mitochondria?

• Cristae increase the surface area for energy production.

• Cristae are critical for the structure of the mitochondria, because they support its shape.

• Cristae denature enzymes that could be harmful to the mitochondria.

• Cristae increase the surface area for photosynthesis to occur.

Multiple Choice

Mitocondria

• Is known as the powerhouse of the cell or power outlet. This is where all the energy is created.

• Shaped like small spheres. Make protein. Can be found in the cytoplasm or attached to rough E.R. look like small polka dots.

• Storage containers that hold water, chemicals, or food for the cell. They are larger in plant cells and smaller in animal cells.
