- Steps of cellular respiration | Biology (article) | Khan Academy
Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation

Unit 7: Cellular respiration About this unit This unit is part of the Biology archive Browse videos and articles by topic For our most up-to-date, mastery-enabled courses, check out High School Biology and AP Biology
- An introduction to cellular respiration (article) | Khan Academy
Through the process of cellular respiration, carbon dioxide and water are also produced During cellular respiration, an organism takes in food (which contains carbohydrates) and oxygen The chemical energy in the carbohydrates is released and stored in ATP, which is used by the organism to power cellular processes
- Photosynthesis and cellular respiration | Khan Academy
Discover the processes that sustain life on Earth! We'll start in the world of cells to understand how enzymes catalyze reactions Then, we'll move on to plants and how they convert sunlight into chemical energy through photosynthesis We'll finish with the process of cellular respiration and how organisms generate usable forms of energy **Unit guides are here!** Power up your classroom with
- Cellular respiration (video) | Khan Academy
Cellular respiration is a chemical process in which the bonds of food molecules and oxygen molecules are broken and new compounds are formed that can transport energy to muscles Cellular respiration also releases the energy needed to maintain body temperature despite ongoing energy transfer to the surrounding environment
- Overview of cellular respiration (video) | Khan Academy
Cellular respiration is how cells get energy from glucose The process has three main parts: Glycolysis happens in the cytosol and breaks glucose into two pyruvate, producing 2 ATPs and 2 NADHs The Krebs cycle occurs in the mitochondrial matrix, where pyruvate is turned into acetyl-CoA, which then goes through a series of reactions, producing ATP, NADH, and FADH2 Finally, oxidative
- Intro to cellular respiration (article) | Khan Academy
Cellular respiration is a biological process in which cells break down glucose in the presence of oxygen, releasing stored chemical energy This energy can be used to power cellular processes
- Oxidative phosphorylation | Biology (article) | Khan Academy
For instance, some intermediates from cellular respiration may be siphoned off by the cell and used in other biosynthetic pathways, reducing the number of ATP produced Cellular respiration is a nexus for many different metabolic pathways in the cell, forming a network that’s larger than the glucose breakdown pathways alone
- Cellular respiration (article) | Khan Academy
Cellular respiration is a process that happens inside an organism’s cells This process releases energy that can be used by the organism to live and grow
- Cellular respiration introduction | Biology (video) | Khan Academy
Cellular respiration is the process by which cells derive energy from glucose The chemical reaction for cellular respiration involves glucose and oxygen as inputs, and produces carbon dioxide, water, and energy (ATP) as outputs There are three stages to cellular respiration: glycolysis, the Krebs cycle, and the electron transport chain
