Transcript of Cellular Respiration

Cellular Respiration
Glycolysis
Anaerobic vs Aerobic Respiration
Cellular Respiration
The process in which heterotrophs harvest electrons from carbon compounds, such as glucose, and use it to make ATP.
Aerobic Respiration
Objectives
I CAN summarize the stages of cellular respiration.
I CAN describe the process of glycolysis
Guiding Question
How are Cellular Respiration and Photosynthesis similar and how are they different?
Anaerobic Processess do not require oxygen.

Aerobic Processess require oxygen.
Do Now
Write question and answer on a Do Now page, with the date in the margin.
1. How is water used during photosynthesis?

a. it provides electrons for the electron transport chain
b. it provides carbon for carbon fixation
c. it provides hydrogen for glucose producation
d. it provides oxygen for use in the plant cell

2. Which of the following is not considered to be a heterotroph?

a. deer
b. human
c. dandelion
d. giraffe
Anaerobic Respiration (Fermentation)
Independent Practice
1. List the stages of cellular respiration.
2. Express the process of cellular respiration as a chemical equation.
3. Clarify the relationship between photosynthesis and cellular respiration.
4. Arrange the following steps in the order in which they occur during glycolysis.
a. Pyruvate (from glycolysis) enters the mitochodria to make more ATP.
b. Two molecules of ATP and two molecules of NADH form.
c. Glucose is broke down into 2 molecules of pyruvate.
5. After exercising for a while, why do you start breathing hard?
Exit Ticket
What is the general equation for Cellular Respiration?

Describe the difference between photosynthesis and cellular respiration.

Why does fermentation take place in the cells of heterotrophs?
Objectives
I CAN summarize the stages of cellular respiration.
I CAN describe and sequence the steps of the Krebs Cycle.
Guiding Question
How does Cellular Respiration ultimately relate to the process of Photosynthesis?
Exam Study Guide
Photosynthesis
- Equation (Reactants and Products)
- Light Dependent Reactions
-Electron Transport
-Products
-Light Independent Reactions
- Calvin Cycle
- Products

Cellular Respiration
- Equation (Reactants and Products)
- Glycolysis
- Krebs Cycle
- Fermentation
Thermodynamics
- 1st Law
- 2nd Law
Energy Molecules
- ATP (structure and function)
Chloroplasts
- Thylakoid
- Stroma
- Chlorophyll (function)
Exam Objectives
I CAN describe the laws of Thermodynamics.
I CAN summarize the stages of cellular respiration.
I CAN describe how ATP works in a cell.
I CAN describe the function of chloroplasts during Photosynthesis.
I CAN summarize the stages of Photosynthesis.
I CAN compare and contrast autotrophs and heterotrophs by describing how they obtain energy.
I CAN describe how Photosynthesis and Cellular respiration are processess that depend on one another.
Aerobic Respiration
Anaerobic Respiration
1. Glucose is broke down into 2 molecules of pyruvate.

2. Two molecules of ATP and two molecules of NADH form.
When oxygen is present, Pyruvate (from glycolysis) enters the mitochodria to make more ATP.
When oxygen is not present, pyruvate is converted to ethyl alcohol or lactic acid in the cytoplasm which are harmful.
Using the textbook and working with your shoulder partner, answer the following in complete sentences. You DO NOT have the write each question.
The Kreb's Cycle
A series of reactions in which pyruvate is broken down into carbon dioxide and ATP and other energy storage molecules are generated.
There are 2 main parts of Cellular Respiration: Glycolysis and Aerobic Respiration.
