Student Worksheet LSM 2.2-3 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 enters the cycle and then combines , which then enters the Krebs cycle. 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 is so it can be used again during the Krebs cycle. CoA– SH CoA– SH CoA– SH Products of the Krebs Cycle 1. 2. is released as waste. and move to the next stage of cellular respiration. 3. Energy is released in the form of molecules of each molecule of Copyright © 2003 Nelson . A glucose molecule produces because two molecules of are created from .

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 . and Coenzyme A carbon atoms, Krebs Cycle Acetyl-CoA creating acetyl – CoA , which then enters the Krebs cycle. 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 NADH CO2 undergoes a number of reactions, releasing and ATP in a number of steps. eventually converted into CoA oxaloacetate Citrate is so it can be 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 ATP 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 . 46 Chapter 2 Cellular Respiration Copyright © 2003 Nelson
