Enzymes
What type of molecule are enzymes made of?
Proteins
What does ATP stand for?
Adenosine Triphosphate.
What is the main source of energy for life on Earth?
The Sun
Only about this percent of energy moves from one trophic level to the next in a food chain.
10%
What percent of users on tik tok are ages 16 to 24?
41%
What is the “active site” on an enzyme?
The active site on an enzyme is the special area where the substrate binds. It has a unique shape that fits only specific molecules, like a key fitting into a lock. This is where the chemical reaction happens, helping the enzyme speed it up.
What is the main job of ATP in a cell?
The main job of ATP in a cell is to store and provide energy for cell processes.
What is a decomposer’s role in an ecosystem?
To break down dead material
ATP is made in this organelle of the cell.
Mitochondria
A vampire doesn’t eat plants, but still depends on photosynthesis. How?
the food the vampire eats gets its energy from producers.
What does it mean when an enzyme becomes denatured?
its shape changes so the active site no longer fits the substrate.
What molecule is formed when ATP loses one phosphate?
ADP
Why does energy decrease at each level of a food chain or energy pyramid?
Energy decreases at each level of a food chain or energy pyramid because energy is lost as heat when organisms use it. Only 10% of energy from each level is passes onto the next.
Enzymes speed up these types of processes in the body.
chemical reactions

Can an enzyme be used again after a reaction? Explain.
An enzyme can be used again after a reaction because it is not changed or used up during the process. After the enzyme helps the substrate turn into products, it’s released unchanged and can catalyze another reaction with a new substrate.
Explain how food helps the body make ATP.
Food helps the body make ATP because it contains chemical energy stored in nutrients like carbohydrates, fats, and proteins. The additional phosphate comes from the food.
What do arrows in a food chain represent?
the movement or flow of energy
This group of organisms captures energy from sunlight and makes food for the rest of the ecosystem.
autotrophs
What famous TikTok singer is currently under investigation for murder after the body of girl was found in his Tesla?
D4vd
What does it mean that enzymes “lower activation energy”?
Activation energy is the amount of energy needed to start a reaction. When enzymes lower activation energy, it means they make it easier and faster for a chemical reaction to happen.
Why do cells need a constant supply of ATP?
Cells need a constant supply of ATP because they are always using energy to stay alive and function properly.
ATP powers essential processes like:
- Active transport (moving materials in and out of the cell)
- Muscle movement
- Cell division and repair
Predict what would happen to consumers if all producers died.
If all producers died, these organisms would eventually starve because they depend on producers (directly or indirectly) for energy.
Explain why enzymes are often called “biological catalysts.”
because they speed up chemical reactions without being used up or changed
