cellular respiration

In glycolysis glucose gets broken into…

2 pyruvate

In pyruvate decarboxylation pyruvate…

Gets broken down into a 2 carbon acetyl group, which binds to Coenzyme A to form acetyl-CoA

In the TCA or Krebs cycle, acetyl CoA…

Combines with oxaloacetate to form citrate or citric acid, which is broken down releasing CO2 and high energy electrons to NADH and FADH2

High energy electrons from NADH and FADH2 are passsed through what

Passed through protein complexes in ETC, pumped across the membrane, creating a proton gradient. (Chemiosmosis - uses the energy from the pumped H+ ions to synthesise ATP from ADP and Pi)

Chemiosmosis

Is the process in which ATP is synthesised in cells using electrochemical gradient of protons (H+) across membrane, during oxidative phosphorylation (mitochondria) and in photosynthesis (chloroplast)

Oxidative phosphorylation

Refers to the entire process of electron transport transfer and ATP production involving ETC and Chemiosmosis

where does glycolysis happen

cytoplasm

where does pyruvate decarboxylation happen?

mitochondrial matrix

where does TCA cycle happen?

mitochondrial matrix

where does electron transport chain happen?

inner mitochondrial membrane

what does glycolysis produce

2 ATP and 2 NADH and 2 pyruvate

what does pyruvate decarboxylation produce (final)

2 acetyl CoA and 2 NADH and 2 CO2

what does Krebs cycle produce?

6 NADH and 2 FADH2 and 2 ATP and 4 CO2

what does electron transport chain produce?

28-32 ATP and H2O

pyruvate decarboxylation what is pryuvate turned into

each pyruvate has 1 CO2 removed, this forms 2 carbon acetyl group. this acetyl group combines to coenzyme A or CoA to make acetyl-CoA
