cellular respiration

aerobic respiration

1. glycolysis
2. krebs cycle
3. oxidative phosphorylation

1. glycolysis

• glucose-> pyruvate
• 2 ATP are added
• 2 NADH are produced
• 4 ATP are produced
• 2 pyruvates are formed

2. krebs(TCA or citric acid) cycle-3 carbon

• OAA+ (pyruvate with coenzyme A->) acetyl coa->citrate->start
• result: 3 NADH, 1 FADH2, 1 ATP, CO2

   3. Oxidative phosphorylation

       Krebs cycle 

       NADH, FADH2  give electrons,  and these electrons energy in ADP to ATP along with ETC

       NADH provides electrons to generate about 3 ATP, while FADH2 generates about 2 ATP
