a. use the word bank to complete the cellular respiration graphic organizer
cellular respiration graphic organizer
step | aerobic or anerobic | location | reactants | products
glycolysis | __________ | ________ | ________ | __________
krebs cycle | __________ | ________ | ________ | __________
electron transport chain | __________ | ________ | ________ | __________
word bank – terms with asterisks are used more than once.

• aerobic* - carbon dioxide - glucose - oxygen
• anerobic - coenzymes - mitochondria matrix - water
• atp* - cytoplasm - mitochondria membrane

Explanation:

• Glycolysis: It is the first step of cellular respiration. It can occur in the absence of oxygen (anaerobic) as well as in the presence of oxygen (aerobic). It takes place in the cytoplasm. The reactant is glucose, and the products are ATP, pyruvate, and NADH (coenzymes).
• Krebs Cycle: It is an aerobic process (requires oxygen). It occurs in the mitochondrial matrix. The reactants are acetyl - CoA (which is derived from pyruvate, and coenzymes are also involved in the cycle). The products are ATP, carbon dioxide, and coenzymes (NADH and FADH₂).
• Electron Transport Chain: It is an aerobic process. It occurs in the mitochondrial membrane. The reactants are coenzymes (NADH and FADH₂) and oxygen. The products are a large amount of ATP and water.

Answer:

Step	Aerobic or Anaerobic	Location	Reactants	Products
Krebs Cycle	aerobic	mitochondria matrix	coenzymes	ATP, carbon dioxide, coenzymes
Electron Transport Chain	aerobic	mitochondria membrane	coenzymes, oxygen	ATP, water
