Respiration

Front 1

Respiration

Back 1

-Oxidation of organic molecules
-Supplies energy in a form available to do work in the cell
-Produces intermediate carbon compounds essential for continued growth and metabolism of cells

Front 2

Anaerobic respiration

Back 2

Does not involve molecular oxygen

Front 3

Aerobic respiration

Back 3

Requires molecular oxygen
occurs in mitochondria

Front 4

Glycolysis

Back 4

-happens in the cytoplasm
-breaking down of glucose

Results
2 molecules of pyruvic acid
4 ATP molecules
2 NADH molecules

Net yield
2 ATP molecules
2 NADH molecules

Front 5

Phosphorylation

Back 5

Preparation of six-carbon sugar for reaction by addition of phosphate from ATP

Front 6

Sugar cleavage

Back 6

Splitting of the sugar phosphate into two three-carbon fragments

Front 7

Pyruvate formation

Back 7

Oxidation of fragments to form pyruvic acid with the formation of NADH and ATP

Front 8

Glycolysis - Aerobic respiration

Back 8

Pyruvate diffuses into mitochondria
-uses 6 molecules of oxygen
-forms 6 molecules of CO2, 6 molecules of H2O + 36 molecules of ATP

Front 9

Glycolysis - Anaerobic respiration

Back 9

-Fermentation forms ethyl alcohol and CO2
-Alcohol produced may be toxic to plant
-Do not oxidize food completely enough to yield enough energy for life processes

Front 10

Rate of respiration

Back 10

quantity of CO2 released or O2 absorbed /unit of cell weight/unit of time

Front 11

Environmental Factors Affecting Respiration

Back 11

-Rate depends on cell type and age
-water content
-Temperature Fluctuations
-Limited photosynthesis influences respiration rate
-Availability of O2
