Detailed explanation-1: -Each turn of the cycle forms one GTP or ATP as well as three NADH molecules and one FADH2 molecule, which will be used in further steps of cellular respiration to produce ATP for the cell.
Detailed explanation-2: -It occurs in the mitochondria in the cell. The number of ATP molecules produced in the Krebs cycle is 2.
Detailed explanation-3: -A total of four CO2, six NADHs, two FADH2, and two ATPs are made through the citric acid cycle. NADH and FADH2 are electron carriers that can produce more ATPs later in aerobic respiration.
Detailed explanation-4: -Products of the Citric Acid Cycle Each turn of the cycle forms three NADH molecules and one FADH2 molecule. These carriers will connect with the last portion of aerobic respiration to produce ATP molecules.
Detailed explanation-5: -The citric acid cycle is a series of chemical reactions that removes high-energy electrons and uses them in the electron transport chain to generate ATP. One molecule of ATP (or an equivalent) is produced per each turn of the cycle.
