It all happens in the cytoplasm and mitochondrion

Anaerobic
• Glycolysis is anaerobic• Fermentation and lactic acid fermentation are
anaerobic• far less ATP ( only 2 per glucose molecule) is
made with out oxygen!

Aerobic Respiration
• Most efficient with oxygen! Up to 38 ATP per glucose.
• Krebs cycle and electron transport are Aerobic.• happens in the mitochondria of eukaryotic
cells.• Electrons have a very strong attraction to
oxygen which is why it is at the end of the electron transport chain!

Glycolysis
• Translated: glyco= glucose• Lysis= split• Splits glucose from 6 carbons into 2 three
carbon molecules called pyruvate. • Happens in the cytoplasm.• Does not require oxygen makes a net gain of 2
ATP and 2 NADH• Requires some energy to get started.

Krebs Cycle
• When oxygen is present pyruvate moves into the mitochondrion. Krebs occurs in the matrix of the mitochondrion.
• A cycle that breaks apart the 2 carbon molecules and forms carbon dioxide and 3 NADH per pyruvate and 1 FADH2 per pyruvate
• 1 ATP directly• It turns 2 times per glucose that goes through
glycolysis.

fermentation
• Occurs in the cytoplasm regenerates NAD+• Makes a small amount of ATP (2)• 2 types • Alcohol and lactic acid• Bacteria and yeast use alcohol fermentation to
make ethyl alcohol and CO2.• Muscles, and microorganisms use lactic acid to
make cheese, yogurt and sour cream

Electron transport chain
• Most important part of the cell respiration process!
• Each NADH can make 3 ATP • Each FADH2 can make 2 ATP• Oxygen is the last electron accepter and forms
water at the end when hydrogen bonds with it.• ATP synthase brings hydrogen ions back across
the inner membrane of the mitochondrion to for the ATP

• Aerobic Cellular Respiration happens in Mitochondria. Three main reactions are involved:
• Glycolosis occurs in cytoplasm of mitochondria (requires 2 ATP to start/ makes 2 ATP)
• Krebs Cycle occurs in matrix of mitochondria (makes 2 ATP)
• Electron Transport Chain occurs in mitochondria; makes majority of ATP (32 ATP)
• Out of 38 ATP Produced - energy of 2 ATP required to start the process.
