Which class of biological polymers has the greatest functional diversity?
Cells store energy for long-term use in the form of fats. 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 are the 4 polymers and their corresponding monomers?
Proteins (polymers of amino acids) Carbohydrates (polymers of sugars) Lipids (polymers of lipid monomers) Nucleic acids (DNA and RNA; polymers of nucleotides)
How are polysaccharides triglycerides and proteins similar?
Dehydration reactions eliminate water from lipid membranes, and hydrolysis makes lip membranes water permeable. Polysaccharides, triacylglycerides, and proteins are similar in that they: are synthesized from monomers by dehydration reactions.
Which of the following is not a true biological polymer?
Triglycerides (a) and glucose (c) are are not considered biological polymers.
At which level of protein structure are interactions between the side chains R groups most important?
The tertiary structure is primarily due to interactions between the R groups of the amino acids that make up the protein.
What is a common feature of both starch and glycogen?
Both starches and glycogen are polymers formed from sugar molecules called glucose. Each independent molecule of glucose has the formula C6H12O, and joining these subunits together in a certain way forms the long chains that make up glycogen and starch.
What is difference between polymer and monomer?
Monomers are small molecules, mostly organic, that can join with other similar molecules to form very large molecules, or polymers. Polymers are a class of synthetic substances composed of multiples of simpler units called monomers. Polymers are chains with an unspecified number of monomeric units.
What are polysaccharides broken down into?
Polysaccharides are broken down into glucose, fats are broken down into fatty acid and glycerol , and proteins are broken down into amino acids.
Which of the following is monomer used to build a biological polymer?
Key terms
| Term | Meaning |
|---|---|
| Monomer | A molecule that is a building block for larger molecules (polymers). For example, an amino acid acts as the building blocks for proteins. |
| Polymer | A large molecule made of repeating subunits (monomers). For example, a carbohydrate is a polymer that is made of repeating monosaccharides. |
Which is not a true polymer?
Carbohydrates, Proteins, and Nucleic Acids are polymers. Answer: D) Fat is not a true polymer.
At which level of protein structure are interactions between the side chains R groups most important quizlet?
Tertiary structure, producing the unique structure of a protein, is stabilized by interactions among the R groups on each amino acid in the protein.
How are macromolecules and polymers related in biology?
Biological polymers are large molecules composed of many similar smaller molecules linked together in a chain-like fashion. The individual smaller molecules are called monomers. When small organic molecules are joined together, they can form giant molecules or polymers. These giant molecules are also called macromolecules.
How are carbohydrates different from other biological polymers?
These polymers are composed of different monomers and serve different functions. Carbohydrates:molecules composed of sugar monomers. They are necessary for energy storage. Carbohydrates are also called saccharides and their monomers are called monosaccharides.
How are monomers linked together in biological polymers?
Biological polymers are large molecules composed of many similar smaller molecules linked together in a chain-like fashion. The individual smaller molecules are called monomers. Monomers are generally linked together through a process called dehydration synthesis, while polymers are disassembled through a process called hydrolysis.
How are polymers responsible for the uniqueness of an organism?
While polymers are responsible for the molecular “uniqueness” of an organism, the common monomers mentioned above are nearly universal. The variation in the form of macromolecules is largely responsible for molecular diversity.
