What some are stringy and fibrous and provide support?

What some are stringy and fibrous and provide support?

Enzymes are particular types of proteins that act to catalyze different reactions or processes. Are fibrous and stringy and provide support. Examples include keratin, collagen, and elastin. Keratins strengthen protective coverings such as hair, quills, feathers, horns, and beaks.

Do nucleic acids provide structural support?

Nucleic acids: Stores and transfers info. Carbohydrates; Store energy, provide fuel, and build structure in body, main source of energy, structure of plant cell wall. Protein: Provide structural support,transport, enzymes, movement, defense.

Do nucleic acids help speed up cellular reactions?

They store energy and help form cell membranes in addition to having other functions in organisms. They form muscles, speed up chemical reactions, and perform many other cellular functions. Nucleic acids are organic compounds that include DNA and RNA.

What macromolecule can provide insulation?

Lipids
Lipids also provide insulation from the environment for plants and animals. Proteins are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macromolecules.

What is meant by nucleic acids?

Nucleic acids are naturally occurring chemical compounds that serve as the primary information-carrying molecules in cells. They play an especially important role in directing protein synthesis. The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

What are the main functions of nucleic acids?

The functions of nucleic acids have to do with the storage and expression of genetic information. Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins. A related type of nucleic acid, called ribonucleic acid (RNA), comes in different molecular forms that participate in protein synthesis.

What macromolecule provides structural support?

Proteins
Proteins are a class of macromolecules that can perform a diverse range of functions for the cell. They help in metabolism by providing structural support and by acting as enzymes, carriers or as hormones. The building blocks of proteins are amino acids.

What macromolecules have structural roles?

For example, macromolecules provide structural support, a source of stored fuel, the ability to store and retrieve genetic information, and the ability to speed biochemical reactions. Four major types of macromolecules—proteins, carbohydrates, nucleic acids, and lipids—play these important roles in the life of a cell.

Do lipids provide structural support?

While lipids are often ascribed a metabolic role as energy storage molecules, they also play important structural and signaling roles in the cell. At each of these levels the structural and signaling aspects of lipids are critical for the cell to mount an efficient response to plasma membrane injury.

Can insulation be provided?

Lipids provide long – term energy storage, form cell membranes (phospholipids). The provide insulation, and cushioning of internal organs, and partake in the messaging process in the body (hormones).

Why are nucleic acids the most important macromolecule?

Nucleic acids are the most important macromolecules for the continuity of life. They carry the genetic blueprint of a cell and carry instructions for the functioning of the cell. DNA is the genetic material found in all living organisms, ranging from single-celled bacteria to multicellular mammals.

How are nucleic acids used to store genetic information?

1 Nucleic acids are macromolecules that store genetic information and enable protein production. 2 Nucleic acids include DNA and RNA. 3 Nucleotides are composed of a nitrogenous base, a five-carbon sugar, and a phosphate group.

Which is a nitrogenous base of a nucleic acid?

Nucleic acids are composed of nucleotide monomers linked together. Nucleotides have three parts: Nitrogenous bases include purine molecules (adenine and guanine) and pyrimidine molecules (cytosine, thymine, and uracil).

How are nucleotides linked together in nucleic acid synthesis?

Phosphodiester linkages form the sugar-phosphate backbone of both DNA and RNA. Similar to what happens with protein and carbohydrate monomers, nucleotides are linked together through dehydration synthesis. In nucleic acid dehydration synthesis, nitrogenous bases are joined together and a water molecule is lost in the process.

Which is an example of a nucleic acid monomer?

Nucleic Acid Monomers. In nucleic acid dehydration synthesis, nitrogenous bases are joined together and a water molecule is lost in the process. Interestingly, some nucleotides perform important cellular functions as “individual” molecules, the most common example being ATP.
