The monomers of proteins are:

Biology
1 answer:
Angelina_Jolie [31]3 years ago
3 0

Answer:

c. amino acids

Explanation:

Amino acids are the monomers of proteins. Two amino acids combine in a condensation reaction that releases water forming a peptide bond. These two amino acid residues form a dipeptide. If a third amino acid is bound, a tripeptide is formed and so on to form a polypeptide.

The amino acids are formed by an alpha carbon attached to a carboxyl group, an amino group, a hydrogen and an R chain of variable composition, which determines the properties of the different amino acids; There are hundreds of R chains so hundreds of different amino acids are known. In natural amino acids, the amino group and the carboxyl group are attached to the same carbon that is called asymmetric alpha.

The binding of several amino acids results in chains called polypeptides or simply peptides. Protein will be discussed when the polypeptide chain exceeds 50 amino acids or the total molecular weight exceeds 5,000 amu. There are about 20 different amino acids composing proteins. The chemical binding between amino acids in proteins occurs through a peptide bond. This reaction occurs naturally in ribosomes, both of the endoplasmic reticulum and the cytosol.

Echinoderms _____. _____ Select one: a. have an exoskeleton of hard calcareous plates b. often use tube feet to move around in t
atroni [7]

Answer:

B. often use tube feet to move around in their environment

Explanation:

Tube feet are tiny tubular projections of echinoderms on the underside (oral side). They are a member of the echinoderm water vascular system.

Tubular feet are used for feeding, breathing and shifting. They are arranged around the sides, in grooves. They work by hydraulic pressure. They are used to transfer food in the centre to the oral mouth, and may stick to surfaces. Tube feet allow certain animals to stick and travel slowly to the ocean floor. for example starfish uses tube feet for the above functions.

Hence, the correct option is B.

The medical term meaning state of complete knowledge (identifying a disease) is:
miv72 [106K]
The medical term is DIAGNOSIS.
Diagnosis is a medical term which refers to the process of determining the disease condition that a patient is suffering from. Accurate diagnosis is made by examining the symptoms of the disease that the patient exhibits. Treatment can only be started after correct diagnosis has been made.

Describe in words what occurs during the process represented by the photosynthesis equation. Include the importance of sunlight
8_murik_8 [283]

Photosynthesis usually takes place in the leaves. Leaf cells contain many chloroplasts (up to 50 per cell). These organelles contain a green pigment, chlorophyll, capable of capturing light energy. This energy is used to make sugar molecules from water drawn from the soil by the roots and carbon dioxide from the atmosphere, captured by the leaves. The sugars produced subsequently distributed in the different parts of the plant.

Here is the reaction of photosynthesis:

6 CO2 + 6 H2O + light energy ==> C6H12O6 (glucose) + 6 O2

But this balance is in fact broken down into two successive stages:

photochemical reactions (clear phase):

12 H2O + light ==> 6 O2 + chemical energy;

the Calvin cycle (dark phase):

6 CO2 + chemical energy ==> C6H12O6 + 6 H2O.

The first phase of photosynthesis, called clear phase, requires the illumination of the leaf. Chlorophyll, which is embedded in the thylakoid membrane, absorbs light energy. This energy absorption is accompanied by the degradation of water molecules and the release of oxygen.

In a second phase independent of light, called the dark phase, the energy absorbed by chlorophyll is used for the transformation of carbon dioxide molecules into sugar molecules.

The sugars made by photosynthesis are stored in the cell as starch, transformed into other organic molecules, such as proteins, or degraded in the mitochondria during respiration to meet the energy needs of the plant.
