Select the correct statements about glycolysis.

Major products of glycolysis include pyruvate, ATP , and NADH .
Glycolysis is the process by which glucose is converted to two molecules of pyruvate.
Two glucose molecules are needed to initiate glycolysis.
Glycolysis is an aerobic process.
Glycolysis occurs in the mitochondria of the cell.

Explanation:

Glycolysis occurs  in nearly all living cell or  organisms.

Glucose provide most of the energy used / produced by cells.

Glucose is the principal source and mainly used in glycolysis for production of energy for cellular metabolism

Products of glycolysis: glycolysis produces two molecules of pyruvate , net gain of two ATP(4-2) molecules, and two NADH molecules.

First half of glycolysis  is known/ called as preparatory phase. In preparatory phase  two molecules of ATP are consumed ,and the second half of glycolysis is pay-off phase, in which 4 molecules of ATP and 2 molecules of NADP are produced.
