The Krebs Cycle Fill in the molecules created or released during the Krebs cycle. Fill in the blanks of the summaries. Pyruvate Oxidation enters the mitochondrion from the cytoplasm. One atom is removed via is removed using becomes attached to the remaining creating and . atoms, Krebs Cycle , which then enters the Krebs cycle. enters the cycle and then combines with to make the six-carbon compound . During the eight steps of the Krebs cycle, undergoes a number of reactions, releasing and in a number of steps. eventually converted into CoA used again during the Krebs cycle.

A glucose molecule produces because two molecules of . are created from is so it can be Student Worksheet Solutions The Krebs Cycle, Solution Fill in the molecules created or released during the Krebs cycle. Fill in the blanks of the summaries. Pyruvate Oxidation Pyruvate enters the mitochondrion from the cytoplasm. One carbon hydrogen atom is removed via is removed using decarboxylation NAD+ . becomes attached to the remaining carbon and Coenzyme A atoms, Krebs Cycle creating acetyl– CoA , which then enters the Krebs cycle. Acetyl-CoA with enters the cycle and then combines oxaloacetate to make the six-carbon compound citrate . During the eight steps of the Krebs cycle, citrate NAD+ CO2 undergoes a number of reactions, releasing CO2 and NADH ATP in a number of steps. eventually converted into CoA oxaloacetate used again during the Krebs cycle. CoA–SH CO2 NADH NAD+ NAD NADH CoA–SH CO2 NAD+ NADH CoA–SH FADH2 FAD GTP GDP ADP + Pi Products of the Krebs Cycle 1. CO2 is released as waste. 2. NADH and FADH 2 move to the next stage of cellular respiration. 3. Energy is released in the form of ATP . A glucose molecule produces two molecules of ATP because two molecules of pyruvate are created from each molecule of glucose . ATP Citrate is so it can be
