Cellular Respiration

Cellular respiration

Cellular respiration

________ is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

citric acid cycle

The ________ occurs in the mitochondria and further breaks down pyruvate into carbon dioxide, producing more ATP and NADH.

Glycolysis

________ occurs in the cytoplasm and breaks down glucose into two pyruvate molecules, producing a small amount of ATP and NADH.

Oxidative phosphorylation

________ occurs in the mitochondria and uses the energy from NADH and another molecule called FADH2 to produce a large amount of ATP.

glycolysis

It occurs in three stages: ________, the citric acid cycle, and oxidative phosphorylation.

Cellular respiration

________ is essential for all living organisms to produce energy for cellular processes.

It occurs in three stages

glycolysis, the citric acid cycle, and oxidative phosphorylation

The overall equation for cellular respiration is

glucose + oxygen → carbon dioxide + water + ATP

Metabolism

Summaration of ALL chemcical reactions

Facultative Anaerobes

organsims pefer using oxygen but if not available it can survive w/ just the anaerobic processes

Obligate aerobes

Organism MUST have oxygen; AKA humans

(they can how ever do some metabolism without oxygen; fermentation)

Aerotolerants

Organisms tolerate oxgen but don’t need it to drive a metabolic reaction

Obligate anaerobes

CANNOT tolerate oxygen; WILL DIE 💀

Prep Step or Pyruvate oxidation

Pyruvates→ into acetyl CoA

Electron carriers & delivers

NADH & FADH2 are _____
