Detailed explanation-1: -The NADH produced in the cytoplasm through glycolysis is transferred to the mitochondria by mitochondrial shuttles. It is used to reduce the mitochondrial NAD+ into NADH.

Detailed explanation-2: -1: Glycolysis produces 2 ATP, 2 NADH, and 2 pyruvate molecules: Glycolysis, or the aerobic catabolic breakdown of glucose, produces energy in the form of ATP, NADH, and pyruvate, which itself enters the citric acid cycle to produce more energy.

Detailed explanation-3: -Energy from ATP is invested into the molecule during this step to energize the separation. The second half of glycolysis extracts ATP and high-energy electrons from hydrogen atoms and attaches them to NAD+.

Detailed explanation-4: -Explanation: Glycolysis creates ATP and NADH through substrate level phosphorylation. The net products are 2 ATP, 2 NADH, and 2 pyruvate molecules. More ATP and high energy electron carriers are produced in the subsequent stages of the metabolic pathway such as pyruvate processing and the citric acid cycle.
