1. Agenda for Monday, December 7, 2015 1.While You Are Waiting #1 2.Hand back quizzes and bell work 3.Photosynthesis/Cell Respiration Video Clip 4.Check Your Homework 5.Details of Photosynthesis and Cellular Respiration 6.Homework: Pages 23 and 24

2. Photosynthesis and Cellular Respiration Videos

3. While You Are Waiting In which organisms will photosynthesis occur? (plants, animals or both) circle one In which organisms will cellular respiration occur? (plants, animals or both) circle one

4. Check Your Homework: 1.Glucose is broken down to make pyruvate 2.Pyruvate is used to make 2 ATP molecules 3.34 ATP molecules are made

5. Check Your Homework: Photosynthesis Cellular Respiration Where in the cell does it occur? What is needed? What is made? Is energy stored or released? chloroplasts mitochondria cytoplasm CO 2 and H 2 O C 6 H 12 O 6 and O 2 stored C 6 H 12 O 6 and O 2 CO 2, H 2 O and ATP released

6. What happens during photosynthesis? Energy from the sun is absorbed by the chlorophyll molecules in the thylakoid membranes of the chloroplast thylakoid Plant cell chloroplast Water is also absorbed by the roots and enters the thylakoid membranes After a series of light dependent reactions, oxygen is produced and released into the atmosphere and ATP and NADPH move to the stroma to be used during the Calvin cycle The Calvin cycle is also called the light independent reaction because it does not require light During the light independent reaction, carbon dioxide, ATP, and NADPH are used to make high energy sugars such as glucose Once ATP and NADPH are used they become ADP and NADP + and move back to the thylakoid to be reenergized 6 H 2 O + 6 CO 2 6 O 2 + C 6 H 12 O 6 stroma

7. What is Cellular Respiration? Glycolysis occurs in the cytoplasm and breaks down glucose to form pyruvic acid, ATP, and NADH In the Krebs cycle, more ATP is produced and NADH and FADH 2 move to the Electron Transport Chain Finally, the E.T.C. uses high energy electrons of NADH and FADH 2 to convert ADP to ATP Through the 3 stages of cellular respiration a total of 38 molecules of ATP is formed per one glucose molecule 2234 6 O 2 + C 6 H 12 O 6 6 H 2 O + 6 CO 2 + ATP - The process of releasing energy from the breakdown of food in the presence of oxygen

8. Interesting Fact about chloroplasts and mitochondria They contain their own genetic information (DNA) which led to the development of the endosymbiotic theory means intomeans living together The theory states that prokaryotic cells lived within primitive eukaryotic cells which developed into the eukaryotic cells that we see today

9. Homework: Pages 23 and 24 Please sit in your seat until the bell rings. Thank you
