Question

the chemical reactions of glycolysis occur without oxygen in the
__________ of the cell.
a chloroplast
b membrane
c cytosol
d mitochondria

Explanation:

Glycolysis is the first step in cellular respiration. It occurs in the cytosol (the fluid portion of the cytoplasm) of the cell and does not require oxygen. Chloroplasts are involved in photosynthesis. Membranes are not the site for glycolysis reactions. Mitochondria are the sites for the later stages of aerobic respiration (like the Krebs cycle and oxidative phosphorylation), but glycolysis itself is not in mitochondria.

Answer:

C. cytosol
