| Where does cellular respiration occur? | In the cells of all living things. |
| What is cellular respiration? | It is a series of energy releasing reactions that break down organic compounds to release chemical energy and transfers it to ATP. |
| Why is energy required in cells? | It is used for movement, making new materials for growth and repair, maintaining internal environments within a narrow range, and detecting and responding to environmental changes. |
| When glucose is broken down in cells the chemical energy in the glucose is lost, how much is harvested as ATP | 40% |
| When glucose is broken down in cells the chemical energy in the glucose is lost, how much is lost as heat energy? | 60% |
| Comparison between Anaerobic and Aerobic Respiration | |
| When is ATP formed? | When ADP reacts with inorganic phosphorus (Pi) |
| Aerobic Respiration Stage 1 Glycolysis | -Occurs in the cytosol of cells -Glucose break down -One glucose molecule is broken down into two pyruvate molecules |
| Aerobic Respiration Stage 1 Glycolysis Cont. | -2 ATP is formed from the release of the energy -Hydrogen atom is removed for the glucose -2 NAD (acceptor molecules) collect the Hydrogen atoms |
| Inputs in Stage 1 Aerobic | Glucose 2 ADP + Pi 2 NAD |
| Outputs in Stage 1 Aerobic | 2 ATP 2 NADH 2 Pyruvate |
| Aerobic Respiration Stage 2 Krebs Cycle | -Occurs in the cell organelles known as mitochondria -2 pyruvate (3 Carbon compound) enters the mitochondria |
| Word Equation Chemical Equation | |
| Aerobic Respiration Stage 2 Krebs Cycle Cont. | -6CO2 (baby 2) formed, and 10 loaded acceptor molecules (8 NADH and 2FADH2 (baby 2)) - 2 ATP is formed -Energy released from this process is used to make ATP and loaded acceptor molecules. |
| Inputs Stage 2 Aerobic | 2 Pyruvate |
| Outputs Stage 2 Aerobic | 6CO2 8NADH 2FADH2 2ATP |
| Aerobic Respiration Stage 3 Electron Transport | -Oxygen essential -Reactions of the loaded acceptor molecules -Occurs in the cristae where cytochromes are found. -Electrons are transferred along cytochromes until accepted by oxygen |
| Aerobic Respiration Stage 3 Electron Transport Cont. | Electrons from NADH and FADH2 combine with oxygen to make the oxygen negative. This allows them to react with the hydrogen to form water. 32 ATP is formed |
| Inputs Stage 3 Aerobic | 8 NADH 2FADH2 |
| Outputs Stage 3 Aerobic | Water Heat Energy 32 ATP |
| Anaerobic Respiration Stage 1 Glycolysis Humans | -Pyruvate produced -Enzyme in muscle tissue converts pyruvate to lactate molecules -loaded acceptor molecules (NADH) drives the conversion of pyruvate to lactate -2 ATP produced |
| Inputs Glycolysis in Humans (Anaerobic) | Glucose |
| Outputs Glycolysis in Humans (Anaerobic) | Lactic Acid (muscle tissues) Heat Energy Water |
| Inputs Glycolysis in Bread and Beer (Anaerobic) | Glucose 2ADP + Pi 2NADH 2 Pyruvate 2 Lactate |
| Outputs Glycolysis in Bread/Beer (Anaerobic) | 2 Ethanol 2CO2 2 Pyruvate 2ATP 2NAD Water |
| Anaerobic Respiration Stage 1 Glycolysis Bread and Beer | -Fermentation -Pyruvate is broken down into carbon dioxide and ethanol -Energy is ATP -2 ATP is produced |
