Which macromolecule holds instructions for cell growth development and reproduction?
What does DNA do? DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.
What macromolecule is used for growth and repair?
Proteins
- Transport molecules in and out of the cell.
- Control the speed of chemical reactions.
- Used for growth and repair.
Which is a function of a protein macromolecule?
The function of the protein macromolecule is to move things in and out of the cell and transport other molecules in the body. There are many functions of proteins. They are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues.
How is DNA linked to the production of proteins?
DNA carries the genetic information for making proteins. The four bases A, T, C and G make up the genetic code. The base sequence determines amino acid sequence in protein.
How is a protein made step by step?
Protein synthesis is the process in which cells make proteins. It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. It includes three steps: initiation, elongation, and termination.
What are 4 examples of proteins?

11.1 Introduction: The Four Major Macromolecules These are the carbohydrates, lipids (or fats), proteins, and nucleic acids.
What are the five main functions of proteins?
5 Roles of Protein
- Building Tissues and Muscles. Protein is necessary in building and repairing body tissues.
- Hormone Production. Hormones are chemicals produced by glands in one part of the body that help coordinate activities and communicate with other areas.
- Enzymes.
- Immune Function.
- Energy.
What do the four groups of macromolecules do?
Macromolecules are just that – large molecules. The four groups of macromolecules, shown in the table below, are essential to the structure and function of a cell. To Identify, Look for . . .
Why are nucleic acids important to the macromolecule?
Study guide: Macromolecule 1.Nucleic Acids 2.Water barrier, insulation, stores energy 3.Fights diseases, builds and repairs tissue, catalyzes chemical reactions, transports materials 4.Nucleic Acids 5.Gives immediate energy and provides structural support 6.Carbohydrates 7.Carbohydrates 8.Proteins 9.Lipids
How are proteins broken down into macromolecules?
Each macromolecule is broken down by a specific enzyme. For instance, carbohydrates are broken down by amylase, sucrase, lactase, or maltase. Proteins are broken down by the enzymes pepsin and peptidase, and by hydrochloric acid. Lipids are broken down by lipases.
How are polysaccharides linked to other macromolecules?
Polysaccharides can be conjugated with other macromolecules. For example, complex carbohydrates can be linked with proteins or lipids to form glycoproteins and glycolipids, respectively. Very different structures can be made from a few monosaccharides arranged in different patterns and with different bonding.
What are the four groups of macromolecules?
The four classes of macromolecules are carbohydrates, proteins, nucleic acids, and lipids. These biomolecules can also be referred to as polymers.
How do you identify macromolecules?
Macromolecules are made of many building blocks, called monomers.They are large molecules that are created by the polymerization of smaller molecules. A macromolecule is constructed in exactly the same way. The word macromolecule means very big molecule. As you know, a molecule is a substance that is made up of more than one atom.
What macromolecule is a cell membrane?
Three macromolecules combine to make cell membranes. Lipids called phospholipids make up most of the cell membrane. Proteins serve as channels, pumps or markers and make up another large portion of the cell membrane. Carbohydrates are also a part of the membrane so cells can recognize each other.
