Final answer:
Glycolysis is an anaerobic process that occurs in the cytoplasm of cells. It is the first step in breaking down glucose to extract energy for cellular metabolism.
Step-by-step explanation:
Glycolysis is the first step in the breakdown of glucose to extract energy for cellular metabolism. It occurs in the cytoplasm of both prokaryotic and eukaryotic cells. Glycolysis is an anaerobic process, meaning it does not require oxygen. Glucose enters the cells through secondary active transport or facilitated diffusion using glucose transporter proteins.
