energy from the sun.
Term
Photosynthesis usually happens in what type of organism?
Definition
Plants
Term
Where are CO2 and O2 found in our enviroment?
Definition
the air
Term
Given what you know about plants, why does your position for CO2 and O2 in the equation make sense?
Definition
Well, plants take in CO2 and release O2, because it's the opposite for animals, so it balances out.
Term
What is the overall purpose of photosynthesis?
Definition
to make food and oxygen.
Term
Use the names of the molecules to explain the process of cellular respiration.
Definition
Uses Glucose and Oxygen to make carbon dioxide, water, and release energy.
Term
Was it difficult to rearrange the pieces to produce the equation for cellular respiration? Why or why not?
Definition
No because you just flip the arrow around.
Term
What is the overall purpose of cellular respiration?
Definition
release energy
Term
What are the main differences between photosynthesis and cellular respiration?
Definition
Photosynthesis uses the stuff that cellular respiration releases, and cellular respiration uses the stuff photosynthesis releases.
Term
What is ATP?
Definition
-Energy used by all cells
-Adenosine Triphosphate
-Organic Molecule containing high energy Phosphate bonds.
Term
Study the chemical structure of ATP, page 135, slide 2.
Definition
go.
Term
What does ATP do for you?
Definition
It supplies you with energy
Term
How do we get energy from ATP?
Definition
By breaking the high-energy bonds between the last two phosphates in ATP.
Term
How do you break the high energy bonds in ATP?
Definition
An enzyme.
Term
When is ATP made in the body?
Definition
cellular respiration
Term
What is the equation for cellular respiration
