Aerobic vs. Anaerobic Respiration 1

Have you ever wondered… Why do your muscles get sore when you exercise? Why does bread rise? The answer has to do with RESPIRATION! 2

What process converts sunlight to glucose? THINK Photosynthesis! What process converts sunlight to glucose? What process converts glucose to ATP? Cellular respiration! What are the reactants of cellular respiration? Glucose & Oxygen 3

Photosynthesis chemical reaction: Reactants Products Glucose, O2 CO2, H2O, Sunlight 4

Respiration chemical reaction: Reactants Products CO2, H2O, ATP Glucose, O2 Cellular respiration usually requires oxygen! 5

Aerobic respiration: respiration WITH oxygen Aerobic respiration produces 36 ATP (LOTS of energy = efficient)

Aerobic respiration takes place in the mitochondria Done by plants and animals 7

Respiration chemical reaction: Reactants Products CO2, H2O, ATP Glucose, O2 Cellular respiration usually requires oxygen! *BUT if there is no oxygen, some organisms can still do respiration! 8

Anaerobic Respiration WORD PARTS: An = not Aerobic = oxygen

Anaerobic respiration: respiration WITHOUT oxygen Anaerobic respiration produces 2 ATP (Little energy = inefficient) 10

Anaerobic respiration takes place in the cytoplasm Done by yeast, bacteria, muscle cells 11

Aerobic or Anaerobic? 12

With oxygen

Little energy production 14

Mitochondria

Yeast 16

Without oxygen 17

Efficient energy production 18

2 Types of ANAEROBIC Respiration 19

1) Lactic Acid fermentation Done by muscle cells when not enough oxygen is available Produces lactic acid (makes your muscles sore!) 20

2) Alcohol fermentation Done by yeast Produces alcohol Causes bread to rise 21

Aerobic or Anaerobic? 22

A yeast cell produces alcohol 23

Occurs in the cytoplasm of the cell

Efficient ATP formation

A cheetah sprints toward prey and its muscle cells produce lactic acid 26

The bacteria that cause tetanus can survive in a puncture wound that has healed on the outer surface of the skin 27

Results in the most energy stored 28

Requires the use of a mitochondrion 29

Yeast cells cause bread to rise 30

Which process releases energy from food by producing ATP in the absence of oxygen? glycolysis fermentation photosynthesis cellular respiration During a biochemical reaction, pyruvate is converted into carbon dioxide and water. In what cellular organelle does this biochemical reaction occur? nucleus cytoplasm mitochondria endoplasmic reticulum

Which process releases the highest amount of energy? anaerobic respiration aerobic respiration photosynthesis protein synthesis The energy required to lift an object is supplied by ATP derived from the break down of molecules of glutamate glycerol glycolysis glucose

Anaerobic Respiration Occurs in the cytoplasm, not the mitochondria.
