Front

What is the monomer of carbohydrates?

Back

Monosaccharide

Answer explanation

The monomer of carbohydrates is a monosaccharide, which is a simple sugar. Other options like amino acids and triglycerides are monomers of proteins and fats, respectively, while nucleic acids are made of nucleotides.

Front

Proteins are made of:

Back

Amino Acids

Answer explanation

Proteins are polymers made up of amino acids, which are linked by peptide bonds. The other options—fatty acids, nucleotides, and monosaccharides—are components of lipids, nucleic acids, and carbohydrates, respectively.

Front

What type of molecule is this?

Back

protein

Answer explanation

The molecule in question is a protein, which is made up of amino acids and plays crucial roles in biological functions, unlike carbohydrates, lipids, or nucleic acids that serve different purposes.

Front

What polymer is made when nucleotide monomers are joined together?

Back

nucleic acid

Answer explanation

Nucleotide monomers are the building blocks of nucleic acids. When these monomers join together, they form polymers such as DNA and RNA, which are classified as nucleic acids.

Front

This macromolecule is made of CHO and provides quick energy to the cell.

Back

carbohydrates

Answer explanation

Carbohydrates are macromolecules composed of carbon, hydrogen, and oxygen (CHO) and are the primary source of quick energy for cells, making them the correct answer.

Front

Unsaturated fats are lipids that are ____ at room temperature?

Back

liquid.

Answer explanation

Unsaturated fats contain one or more double bonds, which prevent them from packing tightly together, making them liquid at room temperature. This distinguishes them from saturated fats, which are solid.

Front

DNA and RNA are examples of:
- lipids
- carbs
- proteins
- nucleic acids

Back

nucleic acids

Answer explanation

DNA and RNA are both types of nucleic acids, which are essential for storing and transmitting genetic information. They differ from lipids, carbs, and proteins, which are other major biomolecules.

Front

The function of this macromolecule is to store and pass on genetic information to offspring. Options: carbohydrates, proteins, nucleic acids, lipids

Back

nucleic acids

Answer explanation

Nucleic acids, such as DNA and RNA, are responsible for storing and transmitting genetic information to offspring, making them essential for heredity. Other macromolecules like carbohydrates, proteins, and lipids do not serve this function.

Front

This macromolecule can form many highly complex structures. Some of the many functions include structural support, speed up chemical reactions, and cell membrane channels.

Back

proteins

Answer explanation

Proteins are macromolecules that can form complex structures and serve various functions, including providing structural support, catalyzing reactions, and forming channels in cell membranes.

Front

Functions of proteins (EXCEPT): catalyze/speed up chemical reactions, make up muscles, hair, and bones, support the immune system

Back

provide quick energy

Answer explanation

Proteins serve many functions, including catalyzing reactions, forming structures like muscles and hair, and supporting the immune system. However, they do not provide quick energy; that role is primarily filled by carbohydrates.
