Target(s): During cell respiration, eukaryotic cells break down organic molecules with oxygen in the mitochondria, which releases energy in the form of ATP, carbon dioxide, and water.

BASED ON THE BOXES FILL IN THE BLANK OF THE WORD EQUATION FOR EACH PROCESS : Photosynthesis : Water + Carbon Dioxide + Sunlight  Oxygen Gas + Glucose REVIEW TARGET: Recognize the equations for photosynthesis and respiration and identify the reactants and products Cellular Respiration: O2 + C6H12O6  H2O + CO2 + ATP Cellular Respiration: Oxygen Gas + Glucose  Water + Carbon Dioxide + ATP NOW WRITE A CHEMICAL EQUATION FOR EACH PROCESS: Photosynthesis: H2O + CO2 + Sunlight  O2 + Carbon Dioxide Glucose Oxygen Gas ATP H20C6H12O6 H20 LAW OF CONSERVATION OF MATTER : Matter is neither created or destroyed, it simply changes form Respiration: Is a process to break down glucose to release energy to make ATP Take place in the mitochondria (PLANTS AND ANIMALS!) Aerobic Process: Uses oxygen Anaerobic Process: Does not use oxygen types

TODAY’S TARGET: During cell respiration, eukaryotic cells break down organic molecules with oxygen in the mitochondria, which releases energy in the form of ATP, carbon dioxide, and water. Aerobic Process: Uses oxygen Respiration w/ oxygen): THREE STAGES FIRST STAGE: GLYCOLYSIS SECOND STAGE: KREB’S CYCLE THIRD STAGE: ELECTRON TRANSPORT CHAIN

TODAY’S TARGET: During cell respiration, eukaryotic cells break down organic molecules with oxygen in the mitochondria, which releases energy in the form of ATP, carbon dioxide, and water. Each stage starts off with 2 ATP molecules In Glycolysis 2 more ATP are made During the Kreb’s Cycle 2 more ATP are made During the Electron Transport Chain up to 34 ATP are made Aerobic Process: Uses oxygen

TODAY’S TARGET: During cell respiration, eukaryotic cells break down organic molecules with oxygen in the mitochondria, which releases energy in the form of ATP, carbon dioxide, and water. Glycolysis breaks glucose into two molecules of pyruvic acid ** Glycolysis ** can happen without oxygen as well. Where does the glucose used in respiration come from? What stages of cellular respiration occur in the mitochondria? How do you know that this is a series of reactions in the presence of oxygen?

TODAY’S TARGET: During cell respiration, eukaryotic cells break down organic molecules with oxygen in the mitochondria, which releases energy in the form of ATP, carbon dioxide, and water. Fermentation: Releases energy from food molecules by producing ATP in the absence of oxygen. Anaerobic Process: Does not use oxygen Lactic acid: Produces lactic acid Alcoholic Fermentation: Produces alcohol and carbon dioxide as waste

TODAY’S TARGET: During cell respiration, eukaryotic cells break down organic molecules with oxygen in the mitochondria, which releases energy in the form of ATP, carbon dioxide, and water. Lactic Acid Fermentation: Occurs in many prokaryotes AND humans when energy is in low supply in muscle cells Anaerobic Process: Does not use oxygen

TODAY’S TARGET: During cell respiration, eukaryotic cells break down organic molecules with oxygen in the mitochondria, which releases energy in the form of ATP, carbon dioxide, and water. Alcoholic Fermentation: Yeast and other microorganisms Anaerobic Process: Does not use oxygen When bread starts to rise it forms the CO2 bubbles and it starts to rise.

TODAY’S TARGET: During cell respiration, eukaryotic cells break down organic molecules with oxygen in the mitochondria, which releases energy in the form of ATP, carbon dioxide, and water. Anaerobic Process: Does not use oxygen DISCUSSION QUESTION: If organisms, such as sea turtles and humans, breath air why would they resort to anaerobic respiration?

TODAY’S TARGET: During cell respiration, eukaryotic cells break down organic molecules with oxygen in the mitochondria, which releases energy in the form of ATP, carbon dioxide, and water. Tanya is on the high school track team and runs the 100-meter sprint. Marissa is on the cross-country team and runs 5-kilometer races. Explain which type of respiration the muscle cells in each runner’s legs use.

TODAY’S TARGET: During cell respiration, eukaryotic cells break down organic molecules with oxygen in the mitochondria, which releases energy in the form of ATP, carbon dioxide, and water.

Anaerobic Process: Uses oxygen It is not just animals that respire – plants do, too! Plants respire all the time because their cells need energy to stay alive. All plant cells need to survive and thrive … not just the green parts.

TODAY’S TARGET: During cell respiration, eukaryotic cells break down organic molecules with oxygen in the mitochondria, which releases energy in the form of ATP, carbon dioxide, and water. What makes AEROBIC unique? What makes ANAEROBIC unique? How are they the same? Partner Discussion Compare/Contrast Aerobic and Anaerobic Respiration: Three unique features of anaerobic Three ways they are similar

TODAY’S TARGET: During cell respiration, eukaryotic cells break down organic molecules with oxygen in the mitochondria, which releases energy in the form of ATP, carbon dioxide, and water.

Anaerobic Process: Uses oxygen Aerobic Process: Uses oxygen Anaerobic Process: Does not use oxygen Energy released 36 ATP or more2-4 ATP ProductsATP, CO2, waterProduces CO2 w/ lactic acid or alcohol WhereCytoplasm and mitochondria StagesGlycolysis, Krebs' Cycle, Electron Transport Chain Glycolysis, Krebs' Cycle SpeedSlower processFaster process in short bursts

TODAY’S TARGET: During cell respiration, eukaryotic cells break down organic molecules with oxygen in the mitochondria, which releases energy in the form of ATP, carbon dioxide, and water. IN SUMMARY: The amount of energy produced by aerobic respiration may explain why aerobic organisms came to dominate life on Earth. It may also explain how organisms were able to become multicellular and increase in size.
