BIOLOGY CH9 Worksheet 1 The Basics
CELLULAR RESPIRATION & PHOTOSYNTHESIS OVERVIEW
PHOTOSYNTHESIS & CELLULAR RESPIRATION
THE BASIC EQUATIONS
PHOTOSYNTHESIS
CELLULAR RESPIRATION
C6H12O6 + O2  CO2 +
+ SUNLIGHT
CO2 + H20 C6H12O6 +
You must know these already!!!
O2
H20
+ ATP
OCCURS IN THE CHLOROPLAST OF AUTOTROPHS
OCCURS IN THE MITOCHONDRIA OF ALL CELLS*
PHOTOSYNTHESIS
+ SUNLIGHT
CO2 + H20  C6H12O6 +
O2
OCCURS IN THE CHLOROPLAST OF AUTOTROPHS
HAS BOTH LIGHT AND DARK REACTIONS
PHOTOSYNTHESIS : The LIGHT Reactions*
+ SUNLIGHT
CO2 + H20  C6H12O6 +
O2
OCCURS IN THE THYLAKOIDS OF CHLOROPLAST
LIGHT REACTIONS- Use light to split H20, make O2,
and a Hydrogen Ion gradient which makes ATP and NADPH
Also known as the LIGHT DEPENDENT REACTIONS
PHOTOSYNTHESIS : The DARK Reactions*
+ ATP + NADPH
CO2 + H20 
C6H12O6 + O2
OCCURS IN THE STROMA OF CHLOROPLAST
The Dark Reactions/Calvin Cycle:
Use CO2 , (+ ATP + NADPH) to make C6H12O6 !!!
Also known as the LIGHT INDEPENDENT REACTIONS AND OR
PHOTOSYNTHESIS:
BOOM, THAT’S IT!!!

BIOLOGY CH9 Worksheet 2 The Basics
CELLULAR RESPIRATION OVERVIEW
C6H12O6 + O2 
CO2 + H20
+ ATP
OCCURS IN THE MITOCHONDRIA OF ALL CELLS*
CELLULAR RESPIRATION
Has a few Reactions
Glycolysis
The Krebs/TCA/Citric Acid Cycle
The Electron Transport Chain
or Fermentation (if there’s no O2 available)
And 2 Major Pathways
Aerobic Reactions – use O2
Anaerobic Reactions – Doesn't use O2
CELLULAR RESPIRATION: Glycolysis
GLYCOLYSIS
C6H12O6 + O2  2ATP + H2O + 2Pyruvate
OCCURS IN THE CYTOPLASM!!!
NOT MITOCHONDRIA
ANAEROBIC REACTION -Doesn’t Use O2
In Short: Step 1
Glycolysis (glucose-lysis)
C6H12O62Pyruvate + H2O +2ATP
CELLULAR RESPIRATION: THE KREBS
CYCLE(*aka. TCA/Citric Acid Cycle)
2 Pyruvate + O2  2ATP + CO2 +2NADH + 2FADH2
OCCURS IN THE MATRIX of MITOCHONDRIA
AEROBIC REACTION –USES O2
In Short: Step 2 The Krebs/TCA Cycle
2 Pyruvate CO2 + 2ATP + 2NADH + 2FADH2
CELLULAR RESPIRATION:
The ELECTRON TRANSPORT CHAIN
The Electron Transport Chain
2NADH+ 2FADH2  H20 + 32-34 ATP
OCCURS ON THE CRISTAE OF THE MITOCHONDRIA
Uses a Hydrogen Ion gradient to make ATP!
In Short: Step 3
The Electron Transport Chain
2NADH + 2FADH2  H20 + 32-34ATP
CELLULAR RESPIRATION:BOOM, THAT’S
IT!!!AGAIN!!...uh oh wait a sec
CELLULAR RESPIRATION: if there’s no O2 Organisms use Glycolysis then Fermentation!!
ANAEROBIC RESPIRATION- AKA- FERMENTATION 2 TYPES
In Animals
In Short: Under Anaerobic Conditons
2 Pyruvate 
+ 2ATP + Lactic Acid
Step 1: Glycolysis
In Yeast
Step 2: Fermentation
2 Pyruvate 
+ 2ATP + Ethanol
