Plant Energy vs Animal Energy How are they different? How are they the same?
The Chloroplast Changes CO2 and Water into Sugar!! Using the Sun to drive the reaction. This is PHOTSYNTHESIS
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 • Changing Light Energy into Chemical Energy Carbon Dioxide + Water + Sunlight--> Sugar + Oxygen 6 CO2 + 6 H2O +Sunlight- - > C6H12O6 + 6 O2 • It happens in 2 Steps • Light Dependent • Light Independent reaction- Calvin Cycle
Light Dependent and Light Independent 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)
The Mitochondria Intermembrane Space Found in both Animals and Plant cells. Changes sugar into ENERGY! This is CELLULAR RESPIRATION !!
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 Sugar • For 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
First two Steps- get us ready for ETC Glycolysis Kreb’s Cycle Glucose 2 Pyruvates • 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
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!!!
