the enzyme
the lemon juice
Which fat type is found in meat and dairy products?
saturated fats
unsaturated fats
trans fats
What is the main role of enzymes?

APPLE LAB: piece of apple on the paper towel.
Where were the enzymes that caused the browning?
in the apple
in the oxygen
there were no enzymes
in both the apple and the oxygen
Which of the following describes this process:
Break down food molecules to add new cells for greater mass and height.
How enzymes identify and attack foreign bodies
The denaturing of enzymes
How children use food molecules to grow taller
The physical breaking down of food into smaller pieces
Which fat type is found in avocados, olives, nuts?
saturated fats
unsaturated fats
trans fats
APPLE LAB: Why did the lemon juice stop the browning?
Lemon juice denatures the enzymes in the apple
Lemon juice denatures enzymes in oxygen
Lemon juice blocks the enzymes in oxygen
Lemon juice binds with oxygen to stop it from working
What does starch (a complex carbohydrate) break down into during chemical digestion?
monomers of glucose
monomers of amino acids
elements C, H, and O
pieces of starch
Choose the term that means:
A process that involves rearrangement of ingredients (reactants) to form new products.
chemical reaction
chemical digestion
denaturing enzymes
mechanical digestion
APPLE LAB: What did the enzyme react with to create the brown color?
Enzymes in the apple react with oxygen
Enzymes in oxygen react with sugar in the apple
Enzymes in the lemon juice react with oxygen
Enzymes in oxygen react with the lemon juice
Choose the term that means:
An organism gets bigger by using food molecules as building materials for new cells.

Claim: breaking down starch is a CHEMICAL REACTION.
Choose all pieces of evidence below that help support this claim.
bonds break
atoms rearrange
new bonds form
new properties created
Choose the term that means:

substrate
enzyme
denature
active site
Choose the term that means:
Chemical messengers, carrying messages from one cell to another.
messenger proteins
transport and storage proteins
enzymatic enzymes
structural proteins
Choose one reason why our bodies break down food molecules.
to create human proteins and carbs from the macromolecules of other organisms
to get elements needed to make muscles and bones
to help the digestive system provide us with energy
to add the proteins and carbs of other organisms into our existing macromolecules
The arrow is pointing to the...
enzyme
substrate
active site
denature
APPLE LAB: Why did the apple piece on the paper towel brown?
Enzymes in the apple react with oxygen in the air and begin to oxidize
Enzymes in the air react with sugar in the apple and begin to oxidize
The enzymes in the apple were denatured causing the browning
The substrate couldn't bond with the enzymes so the apple browned
Choose the term that means:
An organism uses food molecules as building materials to replace old proteins or cells, or to heal from an injury.
growth
repair
polymer

Choose the term that means:
The area where a substrate binds to an enzyme.
substrate
enzyme
denature
active site
Choose the term that means:
Changing an enzyme so that it no longer works.
denature
chemical reaction
mechanical digestion
monomer
Choose the term that means:
Help speed up chemical reactions.

defensive proteins
enzymatic enzymes
structural proteins
Choose all of the correct details about enzymes.
protein molecules
speed up cellular reactions
not permanently changed
break down into glucose
