  • Welcome to Glycolysis.
  • Woww!
  • Did you guys know that NADH are taking electrons to ETC as we work?
  • ATP
  • ATP
  • Glycolysis takes place when oxygen and glucose are present. It takes place in the cytoplasm. In Glycolysis, glucose is broken down.
  • Welcome to the Krebs Cycle.
  • Glucose is broken down to two pyruvate molecules. It's like the glucose is splitting in half because it goes from 6C to 3C (pyruvate). During this process, NAD+ becomes NADH when it gets electrons. The electrons are taken to the Oxidative Phosphorylation.
  • ATP
  • ATP
  • Road trip to the ETC!
  • The pyruvic acid then goes onto the next part, the Krebs Cycle. As a result of gycolysis, CO2 is released and 2 ATPs are made.
  • NADH and FADH2 enter another city, Oxidative Phosphorylation.
  • In order for the process of the Krebs Cycle to occur, there must be oxygen otherwise it won't take place. When the pyruvic acid comes to the Krebs Cycle, it become Acetyl CoA and enters it. NAD+ and FAD are waiting for electrons to take them to the ETC.
  • NAD+ and FAD got the electrons and become NADH ad FADH2. They take the electrons to the next process, ETC. By the end of the Krebs Cycle, it makes 2 ATPs and releases CO2.
  • This process also needs oxygen. The electrons are dropped off by their carriers at Oxidative Phosphorylation. The electron enter the ETC and get passed down. As they pass down, they give off enough energy to pump H+ from the matrix to the intermembrane space.
