Photosynthesis & Cellular Respiration

Definition: The process of using sun energy+CO2+H2O to make glucose Photosynthesis Definition: The process of using sun energy+CO2+H2O to make glucose

Chemical Formula Sun + 6 H2O + 6 CO2  C6H12O6 + 6 O2 Reactants Products Sun +Water + carbon dioxide  Glucose + Oxygen

Occurs in….the chloroplast

Photosynthesis in a nutshell! Sun O2 Glucose CO2 H2O

Cell Respiration Definition: The break down of glucose into 38 ATP for cell energy

6

Chemical formula C6H12O6 + 6O2  6 CO2 + 6 H20 + 36 ATP! Reactants Products Glucose + Oxygen  Carbon dioxide + water + ATP

Occurs in…..the Mitochondria

Cell Respiration Step one: Glycolysis Need: Glucose 2ATP Pyruvate Pyruvate 2 NADH 4 ATP 2ATP Occurs in CYTOPLASM! Nets:

Step 2: Krebs cycle 2ATP Cross into Mitochondria CO2 Pyruvate Pyruvate MITOCHONDRIA MATRIX 2ATP

Step 3: Electron Transport Chain Enzymes + H2O 34 ATP Animation: ETC

Review Occurs across Cristae Occurs in Cytoplasm Occurs in Matrix

CARBON CYCLE  

Energy Define: The ability to do work=move matter Kinetic: Moving energy Potential: Stored energy Thermal: Heat energy Chemical: Stored energy in bonds Calories: The amount of energy needed to decompose stored energy Cell energy: ATP

ATP: adenosine triphosphate Adenosine Triphosphate and Adenosine Diphosphate

What does ATP do for you? It supplies YOU with ENERGY!

How do we get energy from ATP? By breaking the high- energy bonds between the last two phosphates in ATP

How does that happen? An Enzyme! ATPase

ADP
