Question

Site of glycolysis or EMP is

• A. Mitochondria
• B. Cytoplasm
• C. E.R.
• D. Ribosomes

Answer 1

The correct option is B Cytoplasm

Glycolysis is the first step of aerobic respiration in all living organisms. It is an anaerobic pathway which does not require oxygen and takes place in the cytoplasm of cells. This initial process takes place in 10 steps, each one of which is catalyzed by different enzymes. The scheme of glycolysis was first described by Gustav Embden, Otto Meyerhof, and J. Parnas and is often referred to as EMP pathway.

The second and thirds steps of respiration which are Kreb's cycle and Electron transport chain occur in mitochondria of cells and requires oxygen as the enzymes for these steps are present in mitochondria.

ER is an organelle that provides the structural framework to cells and is majorly concerned with the synthesis of lipids and proteins and also responsible for transport of materials.

Ribosomes are the protein factories and are present either on ER or lie freely in the cytoplasm of cells.

Thus, the correct answer is option B.
