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

Beeswax is a waxy substance that is produced by bees and then harvested by humans for a variety of uses. Ancient Romans used beeswax as a waterproofing agent because it is not water-permeable. Beeswax is which of the following types of organic molecule?

Which of the following macromolecules are a prominent part of animal tissues that function in insulation, helping animals conserve heat?

Many plants have waxy coatings on some surfaces. This coating reduces water loss because it is not water-permeable. This waxy coating is which of the following types of organic molecule?

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 biomolecule's function is most likely to be affected by the arrangement of monomers?

The enzymes that catalyze cellular reactions are macromolecules made of organic compounds composed of carbon, hydrogen, oxygen, and nitrogen. These types of macromolecules are known as –

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

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?

In 1960, scientists discovered a molecule that was used to carry genetic information in the nucleus to ribosomes. This information is used to make proteins that are used to perform various functions for an organism.

Which biomolecule is used to transmit genetic information?

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 get nutrients and energy during hibernation by burning stored fat.

In order for hibernation to work, the animal would need to eat a lot of what biomolecule first?

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

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

Lactose is a sugar found in dairy products. The body converts it into a molecule that can be used to make ATP energy.

What type of biomolecule is lactose?

The chart describes several functions and examples of biomolecules.

Which column of biomolecules would accurately complete the chart?

What is the function of proteins in the cell membrane?

During DNA replication, a chemical called DNA polymerase acts as an enzyme to quickly bond nucleotides on the complementary strand. DNA polymerase belongs to a large class of biomolecules that perform most of the actions carried out by organisms called ―

Which of the following is a function of a carbohydrate?

One function of the carbohydrate macromolecule is to store energy. Which other macromolecule also functions in storing energy?

Based on the graph above, at what temperature range is enzyme activity at its greatest?

Ribulose biphosphate carboxylase is a chemical that aides in the process of photosynthesis. Ribulose biphosphate carboxylase breaks down carbon dioxide and bonds carbon atoms together to begin the formation of sugars. Without ribulose biphosphate carboxylase, photosynthetic organisms would not be able to produce as much food. Even though ribulose biphosphate carboxylase is involved in assisting chemical reactions, its chemical structure is unchanged.

Based on the information about the function of ribulose biphosphate carboxylase, what is the best classification of the chemical?

Amylase is an enzyme that helps break down complex carbohydrates into simple carbohydrates. This enzyme is present in the saliva in the mouth and only works in the mouth. When salivary amylase is in the stomach, it stops functioning because the pH in the stomach is acidic.

Which of the following best explains the change that occurs when salivary amylase enters the stomach?

The diagram represents one way an enzyme can be inhibited.

Which statement explains the effect of an inhibitor on an enzyme?

Enzymes are proteins that help increase the rate of chemical reactions inside cells. These proteins are composed of many simpler molecules called amino acids. Which of the following suggests that the shape of an enzyme determines the enzyme’s function?
