Cellular Respiration Cellular respiration is the process in which plants and animals convert FOOD into ENERGY (ATP!) in their cells. This occurs in the Mitochondria! Energy is stored in the form of ATP!! ADP after ATP is broken down
Two types of respiration: (1) Aerobic (uses O2) - Glucose is broken down to CO2 and water with the help of enzymes to produce ENERGY!! 3 stages of aerobic respiration Glycolysis Citric Acid Cycle Electron Transport Chain (2) Anaerobic (doesn t use O2) Glycolysis and Fermentation
It all starts with Glycolysis: Where: In cytoplasm of cells Requires 2 ATP to initiate & produces 4 ATP at the end =net gain of 2 ATP What: Uses glucose from ingestion or PS & breaks it down into pyruvate This pyruvate can be used in 2 ways
Pyruvate moves into the mitochondria and is converted to acetyl-coa
1 st way: Aerobic Respiration Occurs in ALL eukaryotic organisms! Occurs in the mitochondria of cells! C 6 H 12 O 6 + 6O 2 6H 2 O + 6CO 2 + 36 ATP
Why is the Mitochondria a good structure for Cellular Respiration? B/c high surface area on highly folded inner membrane allows for more rxns to occur! LEADS TO MORE ATP!!!
Aerobic Respiration includes Citric Acid Cycle/Kreb s Cycle: pyruvate is modified and carbons from it bond to oxygen to form carbon dioxide, which is released! 2 ATP made! Electron Transport Chain: e- are transported, energy is released & form 32 ATPs! At the end of the chain, the extra Hs bond to oxygen to form water!
Foldable Part 2 Information about Aerobic Respiration (Glycolysis, Krebs Cycle, ETC) Foldable will include who does it, what is the process, where does it occur, when does it occur, how does it occur (i.e. organelle, different processes in different parts of each organelle, reactions, etc)

Please write and complete these sentences! Sunlight is to Photosynthesis as is to Respiration All the time is to Respiration as is to Photosynthesis. Chloroplast is to Photosynthesis as is to Respiration. ATP is to Respiration as is to Photosynthesis.
Analogies of PS and CR Please write and complete these sentences! Sunlight is to Photosynthesis as _Glucose is to Respiration. All the time is to Respiration as daylight is to Photosynthesis. Chloroplast is to Photosynthesis as mitochondrion is to Respiration. ATP is to Respiration as Glucose is to Photosynthesis.
Applying to previous concepts: How are the Biomolecules we just studied in Chemistry related to Photosynthesis and Respiration? Carbohydrates Lipids Proteins Nucleic Acids
Carbohydrates Lipids Proteins Nucleic Acids
Carbohydrates Lipids Proteins Nucleic Acids Glucose is produced during Photosynthesis Make up the membranes of the chloroplast Enzymes control the rate of Photosynthesis DNA controls both processes
Carbohydrate Lipids Proteins Nucleic Acids Glucose is produced during Photosynthesis Make up the membranes of the chloroplast Enzymes control the rate of Photosynthesis DNA controls both processes Glucose is used in cellular respiration Make up the membranes of the mitochondria Enzymes control the rate of Respiration ATP is produced during cellular respiration
Aerobic Vs. Anaerobic Respiration Aerobic Respiration requires O2 Anaerobic Respiration Does not require O2. Also called Fermentation occurs in yeast, bacteria, and muscle cells of animals. This occurs in the cytoplasm of the cell!! Think about bacteria how are they different from all other organisms?
2 types of Fermentation Lactic Acid Fermentation Occurs in the muscle cells of animals Glucose Lactic acid + 2 ATP Sore muscles after exercise! Alcoholic Fermentation Occurs in yeast Glucose Alcohol + CO2 + 2 ATP Used in alcohol production!
