What produces carbon dioxide for plants to use during photosynthesis

Animals

100
The organelle that performs cellular respiration in ALL plant and animal cells.
What are mitochondria?
100
The organelle in which photosynthesis occurs.
What are Chloroplasts?
100

Define active site

The place on an enzyme where the substrate binds

100

Can an enzyme be reused

YES

200

This process will screech to a halt if Texas goes into a major drought in the summer?

What is photosynthesis?

200
The process cells use to take food energy and turn it into ATP.
What is Cellular Respiration?
200

What are the inputs of photosynthesis?

Carbon Dioxide, Water

200

Define enzymes

Protein that speeds up chemical reactions

200
Can substrates be used more than once

NO

300
The energy currency of the cell
What is ATP
300
Glucose and Oxygen
What are the inputs of cellular respiration?
300

What are the outputs of Photosynthesis?

Glucose and Oxygen

300

Define product

The substance that results from a chemical reaction

300

Enzymes end in these three letters

-ase

400

What would happen to human and why if all plant life died

Humans would die. There would be no photosynthesis to remove carbon dioxide from the atmosphere and create oxygen

400
Carbon Dioxide, Water, and ATP
What are the outputs of cellular respiration?
400
It is not a physical input to photosynthesis, but is required for the reaction to proceed. Because of this, we write this form of energy above the arrow in the chemical equation for photosynthesis.
What is sunlight?
400
Define substrate

the molecule upon which an enzyme binds to and acts on.

400

How does an enzyme speed up the rate of a reaction?

By lowering the activation energy.

500
The holes in the bottom of leaves through which carbon dioxide enters the leaf.
What are stomata?
500

What is the chemical equation for Cellular respiration

Glucose + Oxygen ---> Carbon Dioxide + Water + (ATP)

500

What is the chemical equation for photosynthesis?

Carbon Dioxide + Water (+ sunlight) ---> Glucose + Oxygen

500

Define denaturation

The structural breakdown of an enzyme cause it to lose it functionality.
