The human body uses specialized proteins to speed up chemical reactions. These proteins are called enzymes. Without enzymes, the reactions in the body would happen too slowly to keep you alive. Enzymes are made during protein synthesis, which occurs at a cell's ribosomes.

Which biomolecule provides the instructions to build enzymes?

What type of biomolecule is lactose?

Monomers are small molecules that can join together to make larger molecules called polymers. Nearly all of the large molecules in our bodies are a kind of polymer.

Which of the examples are monomers? Select all that apply.

Which of the following are monomer function? Select all that apply.

Which of the following is NOT a polymer function?

Large carbohydrate molecules called polysaccharides are built by joining three or more monosaccharides.

Select all of the examples of polysaccharides.

Which carbohydrate is used for energy storage in plants?

Which carbohydrate is used for energy storage in animals?

What carbohydrate is located in plant cell walls?

What carbohydrate is a simple sugar and can form a ring or chain?

Which is NOT a function performed by carbohydrates? Select all that apply.

Amino acids are building blocks of proteins. Animals can digest proteins, breaking them down into amino acids. These amino acids are then absorbed into the animal and can be used to build proteins again. Proteins can have different shapes and functions.

What is the type of bond that groups amino acids into proteins?

Which of the following is NOT an example of a protein?

Select all of the statements that are TRUE about the group of biomolecules known as nucleic acids.

What is the major function of the nucleotide bases in DNA?

Scientists in Australia have developed a routine for athletes to follow the day before a big race. The routine includes consuming a large amount of carbohydrates. This type of routine is known as "carbo-loading".

Why might consuming a large amount of carbohydrates be beneficial for the athlete during the race?

What is one of the function of nucleic acids?

Which of the following correctly pairs a biomolecule to its function?

When the process of mitosis is correctly completed, the daughter cells should contain exact copies of all of an organism's genes.

Which biomolecule contains all of an organism's genetic information?

Which of the following is a function of a carbohydrate? Select all that apply.

Which of the following macro-molecules is a prominent part of animal tissue that functions in insulation, helping animals conserve heat?

One function of the carbohydrates molecule is to provide energy. Which other macro-molecule also functions in providing energy?

Nucleotide (monomer) = Nucleic Acids

Monosaccharides (monomer) = Carbohydrates

Identify "X"

What is the correct relationship between monomers and polymers?

Which of the following is NOT a lipid?

Many land plants store energy in starch. When energy is needed, the starch molecules can be broken down quickly.

This chemical reaction produces which of the following?

Which of the following macro-molecules are a prominent part of animal connective tissue such as cartilage and keratin?

A biomolecule that is large, complex set of chains composed of alternating sub-units called nucleotides has which of these functions in the cell?

The enzymes that catalyze cellular reactions are macro-molecules called proteins.

Which of the following elements most often compose proteins?

There are four main groups of organic compounds found in cells. One of these groups is carbohydrates.

Which of the following are the primary functions of lipids? Select the two best choices.

Which biomolecule helps build the cell membrane?

Some proteins control chemical reactions in cells. Which of the following is a type of protein that can make it easier for chemical reactions to happen?

Which biomolecule can be stored for later energy source?

Which of the following elements are found in every carbohydrate, lipid, protein, and nucleic acid?

Like other organic compounds found in cells, nucleic acids are made of building blocks.

For example, DNA is made up of four types of _____________, which are often referred to by the letters A, C, G, and T.

Like carbohydrates and lipids, proteins are made up of building blocks.

The building blocks of protein are?

Which of the following are the primary functions of proteins?

Select the three best choices.

The lipids in cells are made up of building blocks. ___________ are the building blocks that can be linked together with other small molecules to male larger, more complex compounds, including fats and phospholipids.

There is one complex carbohydrate that has a unique role in plant cells. This complex carbohydrate does not provide plant cells with energy.

Instead it gives strength and structure to plants. it is the main component of the cell wall.

What is the name of this complex carbohydrate?

Starch and glucose are carbohydrates that can serve as energy sources for cells. To use starch for energy, plants and animals must first break down the starch into glucose molecules.

Many plants that grow in land store energy in the form of starch. When the plant needs energy, the molecules of starch can be broken down into monosaccharides.

What is the process that breaks down polymers into monomers?

Which biomolecule is made of up oxygen, nitrogen, carbon, hydrogen, and phosphorus?

Animals, like bears, hedgehogs, and frogs, hibernate during the cold winter months to conserve energy. Hibernation allows them to survive for long periods of time without needing to eat. Their bodies gen nutrients and energy during hibernation by burning stored fat.

In order for hibernation to work, the animal would need to store what type of biomolecule?
