The chemical reactions that occur in an organism to create energy for the organism to live and function

Why is metabolism important?

Because for an organisms and cells, they need to maintain homeostasis.

How do Enzymes help with metabolism?

By speeding up those reactions.

A type of protein that speeds up chemical reactions. They're known as catalysts

Do Enzymes get used up? Explain

Each enzyme can only work on a specific molecule or type of molecule

What does the shape of an enzyme tells us?

It determines what kind of molecule it will work with.

What happens if the shape of the enzyme changes?

It is considered (destroyed) and can no longer cause reactions

What are the products of an enzyme?

In this reaction the enzyme took two substrates and bound them together to form one new product.

What are the two different things an enzyme can do to substrate?

In this reaction the enzyme turns one substrate into two new products

Explain the Lock-and-Key Model

In this model, the enzyme is the lock, and the substrate is the key.

Explain the Induced Fit Model

This model accounts for the active site of being flexible

Why is it so important for Enzymes to break apart food molecules?

Foods need to be broken so they can be metabolized.

What do carbohydrase do?

These enzymes help break down carbohydrates. They break down complex sugars and starches into simple sugars.

Give examples of carbohydrate Enzymes

Our saliva contains the enzyme amylase which starts to break down carbohydrates in our mouths before it even enters our stomach! Herbivores have an enzyme called cellulose that helps break down plant fibers in their gut.

These enzymes help break down proteins. Proteins are broken down into smaller peptides or amino acids.

An example of Protease is...

The enzyme Pepsin is found in the stomach and begins the breakdown on proteins, while the enzyme Trypsin is found in the small intestines and continues to break down proteins into even smaller parts

Another example of Protease is...

Carnivores rely heavily on protease enzymes to break down their diet of meat, and actually have very little or no amylase to break down carbs in their saliva!

How do Enzymes build larger molecules?

Enzymes can help bring smaller molecules together to build new larger molecules. They can take two substrates and bind them together to form a new product.

What do building Enzymes help do?

This is essential in the building of muscles, in the making of DNA and RNA, and to build proteins.
