HOW ARE THEY DIFFERENT? HOW ARE THEY THE SAME?
Plant Energy vs Animal Energy
Plant Cell vs Animal Cell
Changes CO2 and Water into Sugar!! Using the Sun to drive the reaction. This is PHOTSYNTHESIS
The Chloroplast
Parts of the Chloroplast
Thylakoids – parts of the organelle that hold the chlorophyll Chlorophyll – green pigment that captures the
sunlight for photosynthesis.
Grana – Stacks of thylakoids
Stroma – Fluid that fills the chloroplast, this is where the Calvin Cycle takes place
Photosynthesis
Photosynthesis
Changing Light Energy into Chemical Energy
Carbon Dioxide + Water + Sunlight--> Sugar + Oxygen6 CO2 + 6 H2O +Sunlight- - > C6H12O6 + 6 O2
It happens in 2 Steps Light Dependent Light Independent reaction - Calvin Cycle
Light Dependent Light Independent – Calvin Cycle
Requires Sunlight!
Happens in Grana
Inputs: H2O and Light energy
Outputs: O2, ATP, and NADPH
No Light Required
Happens in Stoma
Inputs: CO2, ATP, and NADPH
Outputs: Sugar (energy)
Light Dependent and Light Independent
Found in both Animals and Plant cells. Changes sugar into ENERGY! This is CELLULAR RESPIRATION !!
The Mitochondria
Intermembrane Space
Cellular Respiration
Changing Sugar into energy our cells can use
Glucose + Oxygen --> Carbon Dioxide + Water + ATP
C6H12O6 + 6 O2 - - > 6 CO2 + 6 H2O + ATP
Products needed - Glucose (sugar) and Oxygen
Creates – Carbon Dioxide, Water and ATP
Source of SugarFor Plants
Sugar is created in the chloroplast Source of energy = Sun
For Animals Sugar comes from our food Source of energy = Fruits, Vegetables,
Meat and Grains!!
There are 3 Steps to Cellular Respiration
Glycolysis : Splits the glucose in half -lysis means to split; glyco- means glucose Happens in Cytoplasm
Kreb’s Cycle: Uses 3 Carbon sugars (Pyruvates), Oxygen and ATP Happens in mitochondria
Electron Transport Chain: Creates the energy we use to grow, reproduce and LIVE Happens in mitochondria
Glycolysis Kreb’s Cycle
Inputs 2 ATP to start Glucose molecule
Outputs 2 ATP Splits glucose into two
molecules
Inputs: 2 ATP (from glycolysis) Pyruvates (from
glycolysis) Oxygen (O2)
Outputs Carbon Dioxide Electron Carriers (NADH
and FADH) 2 New ATP
First two Steps- get us ready for ETC
Glucose 2 Pyruvates
The Electron Transport Chain
It’s a little complicated but let’s break it down.Intermembrane
Space
Inner Mitochondrial Membrane
Matrix Space
Electron Transport Chain
Inputs Electron Carriers (NADH and FADH) from Kreb’s
Cycle ATP (from Kreb’s Cycle) Oxygen
Outputs 32 ATP – This is what we use to Grow, Reproduce and
LIVE!! Water
Electrons (H+) move through the entire membrane and create a total of 32 ATP’s!!!
