1  Aim: How do these athletes get their energy to perform?

2 DO NOW: Trace the fate of a ham and cheese sandwich? HOMEWORK : Textbook pgs. 231, Q’s 1,4 p 236 #8

3  The process of releasing energy stored in the bonds of glucose to a usable form of energy for cells.  All living things must carry out respiration to produce usable energy.

4 Reactants (Raw materials) of Respiration

5 GLUCOSE + OXYGEN

6 Products of Respiration ENERGY + CARBON DIOXIDE + WATER

7 FORMULAS 1. Word2. Chemical C 6 H 12 O 6 + O 2 ATP + CO 2 + H 2 O ENERGY

8  When materials are burned energy is released in the form of heat and light.

9  Glucose is slowly broken down with the help of enzymes.  The energy released is stored in molecules of ATP. mitochondria  The process occurs in the mitochondria which known as the “powerhouse” of the cell.

10  Define cellular respiration.  What are the raw materials of respiration?  What are the products of respiration?  Which type of organisms perform the process respiration?

11  ADPDi  ADP (Adenosine Di-Phosphate) is a low energy molecule  When sugar or foods are “burned” the energy stored in the bonds are used to convert ADP (low energy) ATP (high energy). ADP (low energy) to ATP (high energy)  ADP + P  ATP Animation

12  ENERGY for life functions (used by cells to do work)  Muscle cells have large amounts of mitochondria and therefore they can do great amounts of work.

13 ATP is then created so that its bonds can be broken to provide energy for the cells

14 Cells usually transfer the energy that is released directly to 1. glucose 2. ATP 3. oxygen 4. enzymes Raw Materials? ? ? Products? ? ? ?

15 Energy from organic molecules can be stored in ATP molecules as a direct result of the process of 1. cellular respiration 2. cellular reproduction 3. diffusion 4. digestion

16 1.organisms convert solar energy into the chemical energy found in food molecules 2.respiration occurs in the cells of producers and high-energy molecules enter the atmosphere 3.cells carry out the process of respiration 4.animal cells synthesize starch and carbon dioxide

17 1. DNA 2. Starch 3. Protein 4. ATP diagram below represents a biochemical process.

18 Homework: Photosynthesis/Cell Respiration Review Concept Sheet

19 A C B DO NOW: Copy and complete the chart below and answer the question below. Why is photosynthesis an important process to all living things?

20 Reverse of photosynthesis

21 Produces food (source of energy) for itself & all other organisms

22 All the arrows are associated with the process of 1. carbon fixation 2. photochemical reaction 3. synthesis 4. aerobic respiration ? ? ? glucose ?

25 ATP Water CO 2

26 CO2  Bromoythymal Blue = Indicator for CO2 When CO 2 is present bromoylthymal blue changes

27  Aerobic: with oxygen &  Anaerobic: without oxygen

28 Aerobic cell respiration  Organisms use oxygen in order to “burn” glucose. This is known as aerobic respiration.  Aerobic respiration releases 36 ATP molecules for every one molecule of glucose burned!

29  Bacteria and yeast cells are able to carry out respiration in the absence of oxygen this is called anaerobic respiration.  Anaerobic respiration releases 2 ATP molecules for every one molecule of glucose burned.  This is also called fermentation.

30  Define cellular respiration.  What are the raw materials of respiration?  What are the products of respiration?  Explain the relationship between glucose, ADP and ATP?  Differentiate between anaerobic and aerobic respiration?  Which type of respiration is more efficient and why?  Which organisms primarily use anaerobic respiration?

31  This process of converting glucose into lactic acid, acetic acid, and Ethanol (alcohol) because of an oxygen deficit.  Alcohol, bread and cider are created by a process called Alcohol fermentation.

32 Lactic Acid Fermentation tired muscles burn because glucose was broken down without oxygen. In humans, sometimes tired muscles burn because glucose was broken down without oxygen, this is called lactic acid fermentation. The results are sore painful muscles.

35  Anaerobic respiration produces only 2 ATP molecules for every one molecule of glucose burned.  Aerobic respiration produces 36 ATP molecules for every one molecule of glucose burned!

36 Aerobic respirationAnaerobic respiration Needs oxygenNo oxygen needed All organismsSome bacteria, fungi, muscles Produces 36 ATPProduces 2 ATP Occurs in mitochondriaOccurs in cytoplasm of the cell

37  Bacteria, fungi, protists, plants, and animals!

38  Oxygenglucosemitochondria carbon dioxide  Oxygen and glucose enter mitochondria and carbon dioxide is released.  Carbon dioxide chloroplastoxygen and glucose  Carbon dioxide enters chloroplast and oxygen and glucose are released.

39 1. conversion of radiant energy into chemical energy 2. production of lactic acid as an end product 3. storage of energy in a polysaccharide 4. production of ATP from the breakdown of glucose Summary:

40 In what way are photosynthesis and cellular respiration similar? 1. They both occur in chloroplasts. 2. They both require sunlight. 3. They both involve organic and inorganic molecules. 4. They both require oxygen and produce carbon dioxide.

41 1. It is oxygen released by protein synthesis. 2. It is glucose that was produced in photosynthesis. 3. It is starch that was produced during digestion. 4. It is carbon dioxide released by respiration.

42  The energy made from respiration is used to do what by living cells?  What is muscle fatigue?  What is the relationship between photosynthesis and respiration?  Where in the cell do respiration and photosynthesis occur?
