Location:

(ETC)

Location:

CELLULAR RESPIRATION

Write “cell respiration” down the right

side of your paper

Cellular Respiration takes place in two

locations:

Cytoplasm (Glycolysis)

Mitochondria (Krebs Cycle & ETC)

CELLULAR RESPIRATION

Glycolysis

Occurs in the cytoplasm.

Write this as the location of glycolysis in

the box on your paper.

1. Glucose enters the cytoplasm,

activating glycolysis.

Draw an arrow from glucose to glycolysis

Where did this glucose come from!?!

Generally speaking, what ENTERS

the cell and is USED for cell

respiration?

Generally speaking, what is

PRODUCED and LEAVES the

mitochondria as a result of cellular
