Have homework (Anaerobic Respiration WS) opened on your computer

3. Do Now 2/9/16 What does ATP stand for? What does ADP stand for?
How is energy released in the ATP-ADP cycle?
Define anaerobic respiration.
What is lactic acid fermentation? What is it used for?
What is alcohol fermentation? What is it used for?
Adenosine Triphosphate
Adenosine Diphosphate
Breaking bonds between phosphate groups
Respiration without oxygen
Converts pyruvic acid to lactic acid
Used to make cheese, yogurt
Converts pyruvic acid to ethanol
Used to make bread

4. Review: Anaerobic Respiration
Anaerobic respiration does ____________ require oxygen.
Anaerobic respiration includes _______________ and __________________
Anaerobic respiration produces ____________ molecules
NOT
glycolysis
fermentation
2 ATP

5. Aerobic Respiration Aerobic respiration- does require oxygen to occur
Cellular respiration is the process where sugar and oxygen are used to produce water and carbon dioxide
Aerobic respiration occurs in three steps, it is not a single-step process

6. Three Stages of Aerobic Respiration
Stage 1: Glycolysis
Stage 2: Krebs Cycle
Stage 3: Electron Transport Chain

7. Checks For Understanding
Does aerobic respiration require oxygen or not?
What is the second stage of aerobic respiration?
Yes, it does require oxygen
The Krebs Cycle

8. Glycolysis
Glycolysis- process that splits glucose into 2 molecules of pyruvic acid
Forms 2 molecules of ATP

9. Krebs Cycle Krebs Cycle is also known as the Citric Acid Cycle
Process is described as a series of chemical reactions in which pyruvic acid is broken down into carbon dioxide
This process produces most of the ATP used by the cell and the carbon dioxide that we exhale.

10. Krebs Cycle

11. Checks For Understanding
How many ATP molecules are produced during glycolysis?
What is the other name for the Krebs Cycle?
What gas is produced in the Krebs Cycle?
2 ATPs
Citric Acid Cycle
Carbon Dioxide (CO2)

12. Electron Transport Chain
High energy electrons are generated during the Krebs Cycle to convert ADP to ATP.
Krebs Cycle and Electron Transport Chain (ETC) produce 36 ATP molecules.
These 36 ATPs combined with 2 ATPs from glycolysis mean that a total of 38 ATPs are produced during aerobic respiration.

13. Aerobic Respiration

14. Checks for Understanding
How many ATP molecules are produced in total for aerobic respiration?
In which organelle does aerobic (cellular) respiration occur?
About 38 ATPs
Mitochondria

15. Video https://www.youtube.com/watch?v=-Gb2EzF_XqA
Watch the video on Code Red.
Write down 3 things that you learn from the video at the bottom of your notes.
I will check these during independent practice.

16. Assignment Working silently and independently on the worksheet
On multiple choice questions, if you do not give a short explanation then you will NOT receive credit.
Unfinished classwork will become homework
