Enzymes
Do enzymes speed up or slow down chemical reactions?
Speed up
Is ATP used for quick energy or long-term energy storage?
Quick energy
Does cellular respiration happen all the time?
Yes
Does photosynthesis store energy or release energy?
Store energy
Where does all energy come from?
The sun
What type of macromolecule are enzymes?
Proteins
What happens when one phosphate breaks off ATP?
Energy is released
Is cellular respiration used to make food or release energy from food?
Release energy from food
Is sunlight a reactant or a product of photosynthesis?
Reactant
What is an example of a producer?
Plants, bacteria, algae
How does a change in temperature affect the rate of a reaction?
It speeds up
What does ATP stand for?
Adenine Triphosphate
Which type of organism uses cellular respiration: plants or animals?
Both
Which organisms perform photosynthesis: plants, animals, or fungi?
plants
What is an example of a consumer?
animals, most bacteria, fungi
Why does each enzyme usually work with only one type of substrate?
Because its shape only fits specific substrates
Where is most of the energy stored in an ATP molecule?
In the bonds between the last two phosphate groups
What would happen to a cell if cellular respiration stopped?
The cell would run out of ATP and stop functioning
What are the products of photosynthesis?
Glucose and Oxygen
What does a food chain show?
A single flow of energy and trophic levels
Why does high heat often stop enzymes from working?
Because it becomes denatured (changes shape)
Does ATP or ADP have less phosphates?
ADP (di - 2)
What is the main goal of cellular respiration?
To convert chemical energy in food to chemical energy stored in ATP
What are the reactants of photosynthesis?
Carbon Dioxide and Water
What do trophic pyramids show?
Shows how energy flows through an ecosystem
