Do now activity #5 What is the difference between aerobic and anaerobic respiration? What are the 2 types of anaerobic respiration? What is the difference between the 2 types of anaerobic respiration? What is the formula for cellular respiration? What does cellular respiration produce? What are the 3 steps of cellular respiration?

Section 3-4: energy Essential Question Is energy used or made in photosynthesis? Is energy used or made during cellular respiration? Learning Target Use the chemical equation for cellular respiration to explain how energy stored in food molecules provides energy to the cell. Section 3-4: energy

SUNLIGHT IS THE MAIN SOURCE OF ENERGY FOR LIFE ON EARTH

ALL ENERGY comes from the ____ . sun

There are 3 types of energy: Heat _______ Chemical light

Food stores _________ energy chemical

energy Food is not an usable form of ___________ energy in cells It must be converted to a usable form

ATP Food is changed into Adenosine TriPhosphate (ATP): chemical fuel that powers cell’s activities

ATP: Adenosine Triphosphate

ATP ATP  ADP Terminal phosphate bond is broken Energy is released

ATP ADP = Adenosine DiphosPhate 2 phosphates instead of 3

ATP ADP  ATP Phosphate added ADP

ATP Energy released from ATP is used to… Power active transport Power the sodium- potassium pump Power movement of organelles within the cell ATP

ATP Cells store small amounts of ATP because it is inefficient for storing energy

Energy from carbohydrates used to make ATP from ADP as needed

When you exercise, ATP stored in muscles is used first. Cellular respiration When you exercise, ATP stored in muscles is used first.

Cellular respiration Lactic acid fermentation Muscles low on O 2 begin producing ATP through _______ ___ _____________ .

Lactic acid is eliminated by heavy breathing (taking in more O 2 ). Cellular respiration Lactic acid is eliminated by heavy breathing (taking in more O 2 ).

Electron Transport Chain Cellular respiration Glucose (C6H1206) + Oxygen (02) Glycolysis Krebs Cycle Electron Transport Chain Carbon Dioxide (CO2) + Water (H2O) Cellular respiration can produce ATP for exercise lasting about 30 minutes.

What is cellular respiration’s primary goal? To make energy. But it also produces carbon dioxide & water.

C6H12O6 + 6O2  6CO2 + 6H2O + Energy

photosynthesis Plants are autotrophs that use photosynthesis to make their own ______ . food

as reactants for photosynthesis. Plants need ____ & ____ as reactants for photosynthesis. Water & carbon dioxide

These reactants come from ___ ______ . photosynthesis These reactants come from ___ ______ . Cellular respiration

What is photosynthesis’ primary goal? To make glucose (food) for plants. But it also produces oxygen!

carbon dioxide + water  glucose + oxygen light 6CO2 + 6H2O  C6H12O6 + 6O2 carbon dioxide + water  glucose + oxygen
