Wake-up Briefly explain what happens in Anaerobic respiration. What organisms undergo anaerobic respiration? What does anaerobic mean?

Wake-up Pyruvate is “handled” differently depending on the organism. a. What happens to pyruvate in simple organisms? b. What happens to pyruvate in complex organisms? 2. What does anaerobic mean?

Cellular Respiration II: Aerobic Respiration Christopherson

Purpose of Cell Respiration The process in which glucose (food) is broken down into ATP (usable energy) ATP C6H12O6

Cell Respiration Summative Equation (Formula) C6H12O6 + O2 CO2 H2O ATP + + Reactants Need? Products Produced?

Glycolysis (Simple): Result Glucose is broken down into pyruvate and ATP. The ATP made is enough energy so pyruvate is broken down in ANAEROBIC RESPIRATION through fermentation. C-C-C and C-C-C Pyruvate (ATP) (Fermentation) C6H12O6 C-C-C-C-C-C

Anaerobic Respiration Respiration that occurs without oxygen present

Breaking down pyruvate into waste (trash) Fermentation Breaking down pyruvate into waste (trash) C-C-C and C-C-C Pyruvate (ATP) (Fermentation) Lactic Acid and Alcohol C6H12O6 C-C-C-C-C-C

Glycolysis (Complex) Glucose is broken down into pyruvate and ATP. The pyruvate is then moved to the mitochondria for AEROBIC RESPIRATION to make more ATP. C-C-C and C-C-C Pyruvate (To the mitochondria) (ATP) C6H12O6 C-C-C-C-C-C

Respiration that occurs with oxygen present Aerobic Respiration Respiration that occurs with oxygen present

Organisms that undergo Aerobic Respiration: Complex Organisms (Everything BUT Bacteria and Yeast)

Location Mitochondria: Breaks down sugar into ATP (usable form of energy); Powerhouse of the cell

Mitochondria Structure Cristae: Folded inner membrane Mitochondria Matrix: Inner space in the mitochrondria Animal Cell Plant Cell

Aerobic Respiration: Process 1. A consumer/producer takes in oxygen through respiration O2 C-C-C and C-C-C Pyruvate

Aerobic Respiration: Process 2. A carbon is broken off of pyruvate; combines with O2 and leaves as CO2 O2 CO2 C-C and C-C-C Pyruvate

Aerobic Respiration: Process 3. Pyruvate is stored energy (from sun); when break off a carbon; ATP is created O2 CO2 C-C and C-C-C Pyruvate ATP ATP

Aerobic Respiration: Process 4. The process continues a total of six times; MANY ATP’s are created O2 O2 CO2 CO2 C and C-C-C Pyruvate ATP ATP ATP

Which process produces the MOST ATP Which process produces the MOST ATP? Anaerobic (Glycolysis) or Aerobic Respiration?

What would happen if oxygen was NOT available for Aerobic Respiration? C-C-C-C-C-C Glucose Pyruvate C-C-C and C-C-C O2 Key to the mitochondria ATP ATP ATP ATP ATP ATP ATP ATP ATP ATP

C-C-C-C-C-C C-C-C and C-C-C No OXYGEN LACTIC ACID Our body would switch to anaerobic respiration. The pyruvate would be broken down into waste through lactic acid fermentation. Glucose C-C-C-C-C-C C-C-C and C-C-C Pyruvate No OXYGEN LACTIC ACID Key to the mitochondria ATP ATP ATP ATP ATP ATP ATP ATP ATP ATP

The result: Burning sensation in muscles.

The result: If it went too long, could result in Hitting the Wall.
