The ability of the carboxyl and amino groups to adopt a charge in biology makes
them very important functional groups in proteins. Use the image to choose the
correct statement below?
O Negatively charged regions of molecules tend to have carboxyl groups.
O Positively charged regions in molecules tend to have long carbon chains.
O Only one region of molecule can carry a positive charge at once.
Answers
The correct statement regarding the structure in the above image is as follows: negatively charged regions of molecules tend to have carboxyl groups (option A).
What are amino acids?Amino acids are the monomeric components of proteins. They are any organic compound containing both an amino and a carboxylic acid functional group.
The amino group has a formula -NH₂ while the carboxyl group has a formula -COOH.
According to this question, the ability of the carboxyl and amino groups to adopt a charge in biology makes them very important functional groups in proteins.
As observed in the image of the amino acids, only the carboxyl group carries a negative charge (-), hence, it is correct that negatively charged regions of molecules tend to have carboxyl groups.

When an enzyme binds to its substrate, an enzyme-substrate complex is formed. The activation energy of the reaction is reduced, and the reaction proceeds more rapidly thanks to the complex's provision of certain ions or chemical groups that actually form covalent bonds with molecules at a vital point of the reaction process.

-1- Lipids cannot be considered polymers because
Answers
Answer:
Lipids cannot be considered polymers because, unlike carbohydrates, they are constituted of several units that are different.
Explanation:
Unlike other biomolecules —such as carbohydrates, proteins and nucleic acids— lipids are not considered polymers because the subunits that form them are different, in addition to being made up of a larger molecule, from which they can grow.
Polymers are formed by repeating subunits, having the possibility of forming and growing at either end of their chain. Polymerization is a characteristic shared by carbohydrates, proteins and nucleic acids, but not by lipids.
Lipids are biomolecules of hydrophobic nature formed predominantly by carbon and hydrogen, whose structure can be linear or forming rings. They have biological importance as they are the main component of cell membranes, reserve energy substrate and form molecules such as hormones.

There are proteins in the membrane that have channels for large polar molecules to move into or out of the cell since the plasma membrane is made of a phospholipid bilayer where the inside is non polar. This means large polar molecules need help from proteins to cross the plasma membrane.
In your own words, explain why an organism would require all four of the main biomolecules. What would occur if any of these biomolecules were missing? Are any of the biomolecules more important than the others? Is there one that we could live without?
Answers
Answer:
An organism requires all four main biomolecules because each provides a specific and necessary function for the organism. None of the biomolecules is more important than another, and if any of them were missing, life would not be possible.
Explanation:
The main biomolecules of living beings are carbohydrates, proteins, lipids and nucleic acids, each with a specific function and necessary for the development of life.
The presence of these four biomolecules is necessary because each one fulfills specific and irreplaceable functions, such as:
Carbohydrates: are the main source of energy, forming part of organic biomolecules such as glycolipids, glycoproteins or sugars that form the structure of nucleic acids.Proteins: important for their structural function and for molecules such as enzymes, which contribute to organic functions. They are also part of the cell membranes.Lipids: are the molecules that predominantly form the cell membranes. Additionally, they form functional molecules, such as hormones, and are a reserve energy source.Nucleic acids: DNA and RNA are not only necessary for organic biosynthesis, but also determine the structure and function of each organism. The reproductive and perpetuation function of the species is based on the transfer of genetic material contained in the DNA to the offspring.What would occur if any of these biomolecules were missing?If one of the main biomolecules were missing, the function it provides could not be supplied by another, which would imply the non-viability of a living being. If carbohydrates are missing there is no source of energy, without proteins there would be no tissues like muscle and no enzymes to facilitate organic reactions and without lipids there would be no cells. The absence of nucleic acids, per se, would determine the impossibility of all organic processes.
Are any of the biomolecules more important than the others?No one biomolecule is more important than another. Each one of them fulfills a specific and necessary function that cannot be supplied by another biomolecule.
Is there one that we could live without?All organic molecules are necessary, fulfilling an important function. The lack of any biomolecule in the organism is incompatible with life.
An organism requires all four of the main biomolecules because they're all important for the effective functioning of the organism.
It should be noted that the main biomolecules include protein, lipid, carbohydrates, and nucleic acids. They all play a vital role in how an organism functions.
If any of these biomolecules were missing, the function that can be provided by the biomolecule can't be provided by another biomolecule since they all play different roles. Also, there's no biomolecule that's important than another.

C In active transport, the cell must push or pump the molecules from areas of high concentration to areas of low concentration.
D Molecules called pumps function to control active transport.
Answers
Answer:
D. Molecules called pumps function to control active transport.
Explanation:
Active transport is one of the two types of transport (the other being passive transport). It is the type of transport in which substances move against their concentration gradient i.e. from a lower concentration to a higher concentration. Hence, due to this, energy input in form of ATP is required by the cell.
However, the process of active transport makes use of certain molecules called PUMPS to control it. The pumps moves ions/molecules against their concentration gradient. An example is the sodium-pottasium pump which moves sodium ions from a region of low conc. to a region of high conc.
