Chapter 6-Key Terms Flashcards
What are the 3 main processes of cellular respiration?
- Glycolysis
- Krebs Cycle
- Electron Transport Chain
Where does glycolysis occur?
Cytoplasm
Where does the Krebs Cycle occur?
Mitochondrial matrix
Where does ETC occur?
Mitochondrial cristae
What is yielded in glycolysis?
2 pyruvate molecules
In aerobic respiration, what is pyruvate oxidized into?
Acetyl CoA
Where does pyruvate get converted into Acetyl CoA?
Mitochondrial matrix
Electrons from what molecules fuel the ETC?
NADH and FADH2
Which molecule accepts the electrons at the end of the ETC during aerobic respiration?
Oxygen. Water is then produced.
How many ATPs are produced during aerobic respiration?
38, but it is actually 36 since it takes two ATPs to start the reaction
What type of saccharide is digested to glucose?
Polysaccharide
What do amino acids enter the energy pathways as?
Pyruvate or Acetyl CoA
What are some anaerobic electron acceptors?
Nitrate (NO3) and sulfate (SO4)
What is Aerobic Respiration?
Biochemical pathway that produces ATP by extracting energy from glucose in the presence of oxygen.
Glycolysis is the only process that makes ATP in what energy pathway?
Fermentation
