Messenger RNA (mRNA) carries the instructions for making proteins. Like DNA, proteins are polymers: long chains assembled from prefab molecular units, which, in the case of proteins, are amino acids.

What molecules are monomers of the polymers studied in this chapter?
polysaccharides monomer is a monosaccharide, polypeptide is amino acid, nucleic acid monomer is nucleotide. monomers are built up to be polymers by way of condensation synthesis.
What component in the nucleus is responsible for synthesizing a particular enzyme?
Ribosomes, large complexes of protein and ribonucleic acid (RNA), are the cellular organelles responsible for protein synthesis. They receive their “orders” for protein synthesis from the nucleus where the DNA is transcribed into messenger RNA (mRNA).
What is the polymer for proteins?
Proteins - polymers are known as polypeptides; monomers are amino acids.
What are polymer molecules?
Polymer molecules, or macromolecules, are composed of large numbers of linked, small repeat units. The units from which polymers are synthesized are called monomers. Polymers may be made from one kind of monomer, giving homopolymers, or from several kinds of monomers, giving copolymers.
What molecule is ultimately responsible for putting together a particular enzyme?
The chemical reactants to which an enzyme binds are the enzyme's substrates. There may be one or more substrates, depending on the particular chemical reaction. In some reactions, a single-reactant substrate is broken down into multiple products.
What initiates protein synthesis in a cell by carrying specific instructions from the nucleus to the ribosomes?
Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts. ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes (the structures in which protein synthesis takes place); and transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein.
What part of the cell gives the ribosomes instructions on how do you assemble a protein?
The nucleus (plural, nuclei) houses the cell's genetic material, or DNA, and is also the site of synthesis for ribosomes, the cellular machines that assemble proteins.
Is a protein molecule a polymer?
Proteins are polymers of amino acids. Each amino acid contains a central carbon, a hydrogen, a carboxyl group, an amino group, and a variable R group.
What do storage proteins do?
Storage proteins accumulate in both vegetative and reproductive tissues and serve as a reservoir to be used in later stages of plant development. The accumulation of storage protein is thus beneficial for the survival of plants. Storage proteins are also an important source of dietary plant proteins.
How are proteins polymers?
Explanation: Proteins are made up of hundreds even thousands of amino acids tied together by peptide bonds. ... This reaction can go on indefinitely forming a long chain of amino acids, The long chain of amino acids is called a polypeptide or a protein. As a protein is actually a polypeptide , a protein is a polymer.
What monomers are proteins composed of?
For example, proteins are composed of monomers called amino acids. They are linked together to form a polypeptide chain, which folds into a three dimensional (3D) structure to constitute a functional protein (Figure 1).
How many molecules are in a polymer?
A linear polymer is made up of one molecule after another, hooked together in a long chain.
What are the 3 main types of polymers?
There are 3 principal classes of polymers – thermoplastics, thermosets, and elastomers. Differentiation between these classes is best defined by their behaviour under applied heat. Thermoplastic polymers can be either amorphous or crystalline. They behave in a relatively ductile manner but often have low strength.
What type of molecule are enzymes made from?
Each enzyme is made from proteins made of these twisting and folding amino acids, and therefore the enzyme has a unique shape. This structure is held together by weak forces between the amino acid molecules in the chain.
Which molecule binds to the active site of an enzyme?
The induced fit model states an substrate binds to an active site and both change shape slightly, creating an ideal fit for catalysis. When an enzyme binds its substrate it forms an enzyme-substrate complex.
How do substrate molecules come into contact with an enzyme's active site?
The enzyme 's active site binds to the substrate. ... When an enzyme binds its substrate it forms an enzyme-substrate complex. Enzymes promote chemical reactions by bringing substrates together in an optimal orientation, thus creating an ideal chemical environment for the reaction to occur.
