November 16, 2018

2. How do we grow a plant?
But is that all????

3. I. Photosynthesis Where does this happen in the cell?
Chloroplasts
What type(s) of cell(s) go through this?
Plants
Chlorophyll inside

4. C. Process of Photosynthesis What goes in?
Sunlight (light Energy)
Carbon Dioxide CO2
Water H2O

5. Photosynthesis What comes out?
Sunlight (Light Energy)
Glucose
C6H12O6
Water
H2O
Oxygen O2
Carbon Dioxide
CO2

6. D. Chemical Reaction Let’s write the chemical equation on the board!!
What are the reactants, What are the products?
What type of energy transformations are going on?
Light Energy into Chemical Energy

7. Reaction CO2 + H2O + light O2 + C6H12O6 But it’s not balanced
Products
Reactants

8. II. Cellular Respiration
A. Where does this occur in the cell?
Occurs in Mitochondria
B. What type(s) of cell(s) go through this?
ALL cells must perform this reaction
Not like photosynthesis that only occurs in autotrophs
It’s why we breathe

9. C. Process of Cell Respiration
Carbon Dioxide
CO2
Glucose
C6H12O6
Water
H2O
Oxygen O2
Energy

10. D. Chemical Reaction Let’s draw the chemical formula on the board!!
What are the reactants, What are the products?
What type of energy transformations are going on?
Chemical Energy (Food) into Chemical Energy (ATP)

11. Reaction C6H12O6 + O2  CO2 + H2O + Energy But it’s not balanced
Products
Reactants

12. E. Relationship between Photosynthesis & Cellular Respiration

13. Two Types of Respiration
You are currently taking in oxygen and burning sugars within the mitochondria to release chemical energy.
1. This process is also known as Aerobic Respiration. Why?
Oxygen is present which allows your cells to burn glucose into energy much more efficiently

14. 2. Anaerobic Respiration: Respiration with NO OXYGEN PRESENT
What would happen if your cells were deprived of oxygen?? Would they still be able to burn glucose to make energy??
YES!!
2. Anaerobic Respiration: Respiration with NO OXYGEN PRESENT
a. Example: Fermentation in body cells
Long distance runners often create an anaerobic environment for their cells
Not a very energy efficient process
Bad side effect is produced: Lactic Acid (muscle cramps)

15. b. A different example of fermentation
Breweries rely on this process
Yeast cells need energy to survive, so they will breakdown sugars in anaerobic conditions and the byproduct is alcohol
How do you know CO2 is produced?

16. c. Fermentation Basics Anaerobic Animals produce lactic acid and CO2
Plants produce ethyl alcohol and CO2

17. Efficiency of Types of Cell Respiration
Aerobic respiration yields at least 36 ATP
Anaerobic nets a measly 2 ATP
