Metabolism

Cellular respiration is a multi-step process involving glycolysis, the Krebs cycle, and the electron transport chain, each contributing to the production of ATP. Glycolysis, occurring in the cytosol, converts glucose into pyruvate, generating NADH and a net gain of 2 ATP.

Metabolism

Plant Structure

Can do C3, C4, or CAM Photosynthesis

Chloroplasts

Passes electron to electron acceptor
Cannot absorb green as well
Generates O2
Transform light energy into ATP

Thylakoid

ATP Synthase
H+ Gradient
ETC
Chlorophyll

Cytosol

Grana

Stroma

Cellular Respiration

Electron Transport Chain

Uses a Hydrogen Gradient
Nets 34 ATP
Includes Oxidative Phosphorylation

2. Krebs Cycle

Uses NADH and FADH2

1. Glycolosis

Produces NADH
Changes Glucose to Pyruvate
Nets 2 ATP
Starts in the Cytosol

Photosynthesis

Light Independant

Calvin Cycle

Uses oxidation to lose electrons, reduction to gain them

Carbon Dioxide

Light Dependant

Creates ATP synthase enzyme
Creates NADPH
Photosystem 1
Photosystem 2

Water

Light

Acts as an electron donor

Metabolism

Requires activation energy

Catalysts reduce the energy cost for activation

EXERGONIC
catabolic reactions
digestion
hydrolysis
Uses water in order to break apart an enzyme
(digestion)

Catalysts

Starts in the active site
Require substrates to bond with
RNA
Proteins

Requires the breaking of covalent bonds

Bond-forming reactions

ENDERGONIC
anabolic reactions
synthesis
dehydration synthesis
breaking apart an enzyme and producing water
(synthesis)
