Photosynthesis & Cellular Respiration
2
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
4
Chemical Formula Sun + 6 H2O + 6 CO2 C6H12O6 + 6 O2
Reactants Products Sun +Water + carbon dioxide Glucose + Oxygen
5
Occurs in….the chloroplast
8
Photosynthesis web animation
10
Photosynthesis in a nutshell!
Sun O2 Glucose CO2 H2O
12
Cell Respiration Definition:
The break down of glucose into 38 ATP for cell energy
13
6
14
Chemical formula C6H12O6 + 6O2 6 CO2 + 6 H ATP! Reactants Products Glucose + Oxygen Carbon dioxide + water + ATP
15
Occurs in…..the Mitochondria
17
Cell Respiration Step one: Glycolysis
Need: Glucose 2ATP Pyruvate Pyruvate 2 NADH 4 ATP 2ATP Occurs in CYTOPLASM! Nets:
18
Step 2: Krebs cycle 2ATP Cross into Mitochondria CO2 Pyruvate Pyruvate
MITOCHONDRIA MATRIX 2ATP
19
Step 3: Electron Transport Chain
Enzymes + H2O 34 ATP Animation: ETC
20
Review Occurs across Cristae Occurs in Cytoplasm Occurs in Matrix
21
CARBON CYCLE
22
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
23
ATP: adenosine triphosphate
Adenosine Triphosphate and Adenosine Diphosphate
24
What does ATP do for you? It supplies YOU with ENERGY!
26
How do we get energy from ATP?
By breaking the high- energy bonds between the last two phosphates in ATP
27
How does that happen? An Enzyme! ATPase
28
ADP
30
ATP
32
