4.4 Intro to Cellular Respiration

2.1 Atoms, Ions, and Molecules

  • Set up Cornell Notes on pg. 47

  • Topic: 4.4/4.5 Intro to Cellular Respiration

  • Essential Question:

    1. Describe the relationship between cellular respiration and photosynthesis in a double-bubble map.

1. Describe the relationship between cellular respiration and photosynthesis in a double bubble map.


KEY CONCEPT The overall process of cellular respiration converts sugar into ATP using oxygen.


Try and hold your breath for as long as you can (no cheating).

How did you feel as you were holding your breath?

Why do you think you felt this way?

If you were to run a few miles, what would happen to your breathing?


How does your body use oxygen? cheating).

  • Oxygen helps your body break down chemical energy that is stored in sugars and other carbon based molecules.

  • The energy produced is ATP

ATP


Pg. 46 cheating).

Compare the reactants and products. What do you notice?


  • Plants use cheating). photosynthesis to make their own food

  • Animals eats other organisms as food

    • Food is not the direct source of energy

      • Instead we break down molecules from food to produce ATP

  • Cellular respiration releases chemical energy from sugars (produced by photosynthesis) and other carbon-based molecules to make ATP when oxygen is present


  • Two “Stages” cheating).

  • Light Dependent- ETC-Fuels Light Independent

  • Light Independent- Calvin Cycle- Makes Glucose

  • Two “Stages”

  • Stage I- Kreb’s Cycle- Fuels Stage II

  • Stage II- ETC- Makes lots of ATP!



There are two main parts to a mitochondria: cheating).

  • The reactants in photosynthesis are the same as the products of cellular respiration.


  • Glycolysis cheating). must take place first. It happens in the cell’s cytoplasm

  • anaerobic process (does not require oxygen)

  • splits glucose (from photosynthesis) into two three-carbon molecules called pyruvates

  • produces two ATP molecules

2 pyruvate

“Sweet Split”

ATP


  • Cellular respiration cheating). releases chemical energy from glucose (produced by photosynthesis) and other carbon-based molecules to make ATP when oxygen is present

  • Cellular respiration is aerobic, or requires oxygen.

Stage I

  • The Krebs cycle takes place inthe mitochondrial matrix

    • 2 pyruvates enter cellular respiration

  • Pyruvates are broken down and ATP is made during the Kreb’s Cycle

  • ATP transfers energy-carrying molecules to Stage II: The Electron Transport Chain

  • releases carbon dioxide as waste

Stage II

  • The electron transport chain produces a large amount of ATP and takes place in the inner membrane

  • 3. energy transferred to proteins in the inner membrane

  • 4. oxygen enters process and is used to make H2O

  • A large number of ATP molecules are produced

  • water and heat are released

Photosynthesis & Cellular Respiration Pg. 115 in book

2.1 Atoms, Ions, and Molecules

  • Set up Cornell Notes on pg. 49

  • Topic: Photosynthesis & Cellular Respiration

  • Essential Question:

  • What is the difference between aerobic and anaerobic processes.

  • What processes in cellular respiration are aerobic? Anaerobic?

  • What is the difference between aerobic and anaerobic processes.

  • What processes in cellular respiration are aerobic? Anaerobic?


EQ: Please create a Double-bubble map comparing and contrasting Photosynthesis and Cellular Respiration.
