Detailed explanation-1: -Glycolysis is the first phase in cellular respiration where glucose is converted into pyruvic acid and 2 ATPs are produced. This process takes place in the cytoplasm. Pyruvate is the end product of glycolysis that can be used in either anaerobic respiration or aerobic respiration.

Detailed explanation-2: -Glycolysis, the first step of cellular respiration, occurs in the cytoplasm of your cells. During this process, a glucose molecule is broken down into two molecules of pyruvate (pyruvic acid).

Detailed explanation-3: -Glycolysis ultimately splits glucose into two pyruvate molecules. One can think of glycolysis as having two phases that occur in the cytosol of cells. The first phase is the “investment” phase due to its usage of two ATP molecules, and the second is the “payoff” phase.

Detailed explanation-4: -The glycolysis process results in the production of two molecules of 3-carbon pyruvate and two molecules of an electron acceptor called nicotinamide adenine dinucleotide (NAD). This process also produces two molecules of adenosine triphosphate (ATP). Therefore, the correct option is B.
