Cellular Respiration Photosynthesis and ATP ATP ENERGY ATP

Cellular Respiration, Photosynthesis, and ATP

ATP = ENERGY ATP = Adenosine Triphosphate 1 Adenosine molecule 3 phosphate groups 1 sugar called, Ribose

ATP = Adenosine Triphosphate Adenine + Ribose 3 PHOSPHATE

Adenosine Molecule Phosphorous Ribose Sugar

Making and Breaking ATP Energy is released when a bond is broken between one of the three phosphates

BROKEN BONDS When a ATP loses a Phosphate it becomes Adenosine Diphosphate ATP can be made again by adding another phosphate. Energy is used to do this.

What do we use ATP for? • Obtain food • Transport materials in our body • Eliminate waste • Look for the remote control for the TV

What organelle makes ATP? ? • MITOCHONDRIA

Mitochondria • Mitochondria performs cellular respiration • Cellular respiration AKA Aerobic respiration • Cellular respiration breaks down food (glucose) to make ATP

Ingredients for Cellular Respiration • Mitochondria needs: • Glucose (C 6 H 12 O 6) and • Oxygen (O 2)

Mitochondria makes 1) ATP 2) carbon dioxide (CO 2) 3) H 20 • • •

• The scientific equation is written like this: • C 6 H 12 O 6 + O 2 CO 2 + H 2 O + ATP

Where do you think the Mitochondria gets the oxygen and molecule of glucose to start with? ?

If you said photosynthesis you were correct!

Photosynthesis Chloroplasts make glucose and oxygen Photosynthesis specifically happens in the thylakoid membrane of the chloroplast

Photosynthesis Starts with: • • 1) Carbon Dioxide (CO 2) • 2) H 20

Photosynthesis • Photosynthesis makes: • 1) Glucose • 2) Oxygen

Photosynthesis Equation C 02 + H 20 + sun C 6 H 1206+O 2 START: Carbon dioxide and water Product: Glucose + Oxygen

• Think, where do plants get the carbon dioxide and water from? ? ?

US!!! • It’s a cycle!

Photosynthesis Cellular Respiration Glucose broken Glucose is made down Energy of glucose Energy is stored if broken down Oxygen is taken in released Carbon dioxide is is taken in released
