WebIn glycolysis, the beginning process of all types of cellular respiration, two molecules of ATP are used to attach 2 phosphate groups to a glucose molecule, which is broken down into 2 separate 3-carbon PGAL molecules. PGAL releases electrons and hydrogen ions to the electron carrier molecule NADP+. WebAnswer 1. NADPH is produced in the light reactions during photosynthesis by NADP reductase located in photosystem II in chloroplast . Then NADPH used in carbon fixation in Calvin cycle. Answer 2.

WebAcetylcoenzyme A initiates the citric acid cycle. The citric acid cycle releases sixteen hydrogen atoms. These hydrogen atoms must be transferred through the eight steps of the citric acid cycle. This is carried out by nicotinic adenine dinucleotide (NAD+). Each NAD+ is converted to NADH in three steps of the citric acid cycle. great hormead harveyWebAug 13, 2024 · The Citric Acid Cycle: Capturing Energy from Pyruvate Aerobic respiration begins with the entry of the product of glycolysis, pyruvate, into the mitochondria. For each initial glucose molecule, two pyruvate molecules will enter the mitochondria.
