Macromolecules

Macromolecules are large molecules made up of smaller molecules joined together. The four main groups are proteins, lipids, carbohydrates and nucleic acids. They are essentially for proper cellular functioning.

755 Questions

What macromolecule provides short-term energy storage for plants?

Starch, which is a complex carbohydrate, provides short-term energy storage for plants. It is composed of multiple glucose units linked together and is stored in plant tissues like roots, tubers, and seeds. Starch can be broken down into glucose quickly to provide energy for plant metabolism and growth.

Which macromolecules are made of repating small units?

Polysaccharides, proteins, nucleic acids, and some lipids are macromolecules made of repeating smaller units. Polysaccharides consist of repeating sugar units, proteins of amino acids, nucleic acids of nucleotides, and some lipids of hydrocarbon chains.

What subunits are used to make 4 macromolecules?

The subunit of carbohydrates is glucose.The subunit of nucleic acids is a nucleotide. The sub unit for protein is an amino acid. Lipid sub units are fatty acids and gylcerol.

What is the macromolecule in a corn plant?

Corn has more than one macromolecule: Carbon, Nitrogen, Oxygen and Hydrogen are the major nutrients that make up a corn plant and the macromolecules of that plant.

What macromolecules form skin blood hair muscles?

Skin, blood, hair, and muscles are primarily composed of proteins, which are macromolecules made up of amino acids. Collagen and keratin are specific proteins found in skin and hair, while hemoglobin is a key protein in blood. Additionally, muscle tissue consists of contractile proteins such as actin and myosin. Lipids and carbohydrates also play supportive roles in these tissues.

What type of macromolecule is lactose and what is the monomer of that macromolecule?

Lactose is not a macromolecule. It is a disaccharide, that is one molecule of lactose is formed by the elimination of water between two simple sugar molecules, in this case galactose and glucose. Lactose can be made to link up into medium chain molecules, but this is a fairly random process and produces a mixture of products which are not digestible.

What macromolecule is water?

No, water is a very small number, consisting of only three atoms and having a molecular mass of approximately 18 AMU.

What kind of macromolecules are built from carbon atoms that living organisms obtain from the carbon cycle?

All of them since they are organic. Lipids, proteins, carbohydrates and nucleic acids are considered to be the 4 groups of biological macromolecules.

Is DNA in archea?

actual histone particles are not present in archaebacteria

they have some other type of dna binding protein

Are monomers made up of many polymer units?

No.

Amino acid monomers are used to make protein polymers.

Nucleotide monomers are used to make DNA polymers.

Which term identifies a reaction breaks apart macromolecules?

The term that identifies a reaction that breaks apart macromolecules is "hydrolysis." In hydrolysis, water molecules are used to break the bonds holding macromolecules together, resulting in the formation of smaller molecules or monomers.

What kind of macromolecules are insulin and hemoglobin?

They are type of proteins. They are made up of amino acids

What is true of all macromolecules?

Macromolecules are formed from many simple molecules (monomers) and have a big molecular mass.

What class of macromolecules does enzyme belong to?

DNA polymerase is an enzyme that helps catalyze the polymerization of DNA bases (deoxyribonucleotides) into a DNA strand.

What foods do not contain macromolecules?

of the choices:

proteins

starches

nucleotides

lipids

nucleotides are not macromolecules

What are some different types of macromolecules and examples?

The four major macromolecules are: lipids, carbohydrates, nucleic acids and proteins.

Lipids: Ear Wax

Carbohydrates: Glucose, Sucrose, Lactose

Nucleic Acids: DNA and RNA

Proteins: Everywhere! Muscles, skin, and hair.

What is the role of DNA helicase during DNA replication?

DNA helicase "unzip," or separate, a strand of DNA at positions called origins. This means that the hydrogen bonds between complementary base pairs are removed (DNA is double stranded!). When they separate double-stranded DNA into single strands, it allows each strand to be copied (replication).

DNA helicases use the energy stored in a molecule called ATP to break the bonds, which serves as the energy currency of cells.

What class of macromolecules do phospholipids belong to?

The lipids are the only class of macromolecules that contain fatty acids, steroids, phospholipid, and more.

What are the basic units for protein macromolecules?

Amino Acids are the basic monomer units of proteins. There are 20 kinds of amino acids that can be used in a protein. Proteins vary in the amount and sequence of these amino acids as well as their final folded structure.
