Tutorial

En esta lección vamos a discutir los procesos que ocurren en el ciclo Krebs para producir ATP para la célula.

Overview

(0:00-1:18) Overview of the Krebs cycle

(1:19-2:14) Prep Steps of the Krebs Cycle

(2:15-5:57) The Krebs Cycle

Terms to Know
Acetyl CoA

A molecule produced from pyruvate which enters the Krebs cycle to produce ATP.

Coenzyme A


An enzyme used to change pyruvate into acetyl CoA which enters the Krebs cycle.

FADH2 and FAD

FAD is a molecule that picks up hydrogen atoms and becomes FADH2 which is then transferred to the electron transport chain to produce more ATP from the energy in electrons.

NAD+ and NADH

NAD+  is a molecule that picks up hydrogen atoms and becomes NADH which is then transferred to the electron transport chain to produce more ATP from the energy in electrons.

​Krebs Cycle

The second stage of cellular respiration in which pyruvate from glucose is used to produce ATP, NADH and FADH2.
