Cellular^ Respiration:

(2^ kinds—Aerobic

and^ Anaerobic)

  • Cellular^ respiration

is^ the^ process

by^ which^ the

energy^ of

glucose^ is^ released

in^ the^ cell^ to

be^ used^ for

life^ processes

( movement,

breathing,

blood^ circulation

,^ etc…)

  • Cells^ require

a^ constant^ source

of^ energy^ for

life^ processes

but

keep^ only^ a^ small

amount^ of^ ATP

on^ hand.^ Cells

can^ regenerate

ATP^ as^ needed

by^ using^ the

energy^ stored

in^ foods^ like

glucose.

  • The^ energy

stored^ in^ glucose

by^ photosynthesis

is^ released^ by

cellular^ respiration

and^ repackaged

into^ the^ energy

of^ ATP.

  • Respiration

occurs^ in^ ALL

cells^ and^ can

take^ place

either^ with

or^ without

oxygen^ present.

Step^ 1:^ Glycolysis

-^ Glycolysis

^ split^ glucose (sugar)

-^ Occurs^ in^

cytosol (cytoplasm)

-^ Reactants^ •^ Use^2 ATP

to^ split^ glucose

into pyruvate • Rearrange^ resulting compounds • Products • 4 ATP^ &^ pyruvate • 4 ATP‐^2 ATP=

Step^ 2:^ The

Krebs^ Cycle

-^ Occurs^ in^ the

matrix st^ • 1 Reactant :^ Pyruvate st^ • 1 Products :^ CO^ ,^ NADH,^2 acetyl CoA nd^ • 2 Reactant :^ Acetyl^ CoA begins Krebs cycle nd^ • 2 Products :^ CO^ ,^ NADH,^2 (2)ATP, and FADH^2
