sketch the bonding of two amino acids, glycine and leucine, by a peptide linkage. now add a third amino acid, alanine, in the position it would have if added within a biological system. what is the directionality of this process?

Answers

Answer 1

The amino end of a polymer is always converted to the carboxy end.

What is polymerization?

The process of creating polymers is called polymerization. Following processing, these polymers are used to create a variety of plastic items. Smaller molecules, or monomers, are joined chemically to form larger molecules, or macromolecules, during polymerization.

The carboxyl end of the final amino acid in the sequence combines with the nitrogen group of a new amino acid in accordance with the directionality of polymerization. As a result, leucine and alanine will be connected.

The directionality of this process will be amino end to carboxy end.

certain vitamins or provitamins have antioxidant properties that help protect against free radical damage to cells. check all of the following substances that have antioxidant activity.

Answers

Vitamin C, Vitamin E, and beta-carotene have antioxidant properties that help protect against free radical damage to cells.

Free radicals are unstable chemicals that the body creates in response to external and other stresses, and antioxidants are compounds that can stop or decrease the damage that free radicals do to cells. The origins of antioxidants could be either natural or synthetic, and they are sometimes referred to as "free-radical scavengers." A carotenoid is a class of chemical that includes beta-carotene. Plants that are reddish-violet in hue, such carrot, sweet potatoes, and apricots, contain carotenoids. Among provitamins is beta-carotene. It follows that your body uses it to produce vitamin A. Both vitamin C and vitamin E have antioxidant properties. Water-soluble vitamins are more easily retained in tissues because they are directly taken into the blood.

During glycolysis, a 6-carbon sugar diphosphate molecule is split into two 3-carbon sugar phosphate molecules. True or false?.

Answers

The given statement is true. During glycolysis, a 6-carbon sugar diphosphate that is fructose-1,6-bisphosphate is splitted into two 3 carbon sugar phosphate molecules that are dihydroxyacetone phosphate and glyceraldehyde-3-phosphate.

What is glycolysis?

Glycolysis is a 10-step reaction wherein glucose is divided into two pyruvate molecules, each of which has three carbons.

Glycolysis is the initial step in the process of cellular respiration in organisms. However, many anaerobic organisms also contain this route since glycolysis does not require oxygen.

What are the various steps involved in glycolysis?

1. The conversion of D-glucose into glucose-6-phosphate is the initial step in the glycolysis process. The enzyme catalyst in this case is hexokinase.

2.This second phase involves the conversion of fructose 6-phosphate  from glucose 6-phosphate.

3. Using magnesium as a cofactor, fructose 6-phosphate is changed into fructose 1,6-bisphosphate.

4. Fructose 1, 6-bisphosphate is split into two identical sugars by the enzyme aldolase. Dihydroxyacetone phosphate (DHAP) and glyceraldehyde 3-phosphate are the names of these two sugars.

5.The molecules glyceraldehyde 3-phosphate and dihydroxyacetone phosphate (DHAP) are quickly interconverted by the enzyme triphosphate isomerase.

The first five steps listed above are regarded as the initial phase.

.Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) converts glyceraldehyde 3-phosphate into 1,3-bisphosphoglycerate by dehydrating it and adding an inorganic phosphate.

7. To create ATP and 3-phosphoglycerate, a phosphate group from 1,3-bisphosphoglycerate is transferred to ADP.

8. In this step, Phosphorous from 3-phosphoglycerate is transferred from the third carbon to the second carbon to generate 2-phosphoglycerate.

9. An enzyme removes a water molecule from 2-phosphoglycerate to create phosphoenolpyruvic acid (PEP).

10. Phosphoenol pyruvic acid is converted to pyruvate.

Cells use the process of glycolysis to break down glucose and produce ATP as a source of energy (adenosine triphosphate). There is no need for oxygen because the process takes place in the cytosol of cells (anaerobic). All cells use the same pathway to produce energy, and it is the first stage in the breakdown of glucose to do so.

Sexual reproduction promotes genetic variation. One way variation occurs is via the production of gametes during meiosis. Sexual organism are the product of sperm and egg, receiving chromosomes from both parents. But what mechanisms are at work during meiosis to promote genetic variation? Review the prompt and select all that apply

Answers

Independent assortment that promotes genetic variety is a chromosomal assortment and crossing over. Thus, options are -

(A) Crossing over

(D) Random segregation

(E) Independent assortment

What happens during meiosis?

During the metaphase stage of meiosis, the chromosomes align in the center, and either the mother's or father's chromosome has an equal chance of being transferred to the daughter's cell. The bigger the number of chromosomes in a karyotype, the greater the likelihood of gamete diversity.

During meiosis, homologous chromosomes cross across, allowing DNA fragments to be exchanged between sister chromatids. This results in variation.

Thus,

(A) Crossing over occurs when homologous chromosomes join up with non-identical twins and swap DNA sections.

(D) The distribution of chromosomes among four gametes is known as random segregation.

(E) Independent assortment entails the separation of a pair's homologous chromosomes into distinct gametes.

status, trends, and equilibrium abundance estimates of the translocated sea otter population in washington state

Answers

Prior to their local extinction in the early 1900s as a result of the marine fur trade, sea otters (Enhydra lutris kenyoni) once lived in Washington State, USA.

After being extinct, 59 sea otters were brought from Amchitka Island in Alaska, USA, to the coast of Washington. Of these, 29 were released in 1969 at Point Grenville and 30 in 1970 at La Push.

Estimates of the translocated sea otter population's status, trends, and equilibrium abundance in Washington State

A chosen sample level and a target geographic distribution are the two key goals set forth by the Washington Department of Fish and Wildlife for the recovery of sea otters. Estimations of these characteristics have significant management consequences because recovery requirements are dependent on estimates of populations abundance, equilibrium abundance, and geographic distribution. In order to assess history and present abundance as well as equilibrium abundance at various spatial scales, we collated all survey data for sea otters that have been recorded in Washington State since their relocation (1977–2019). As a foundation for a sensitivity analysis to gauge the relative impact of movement behavior, in Journal of Wildlife Management, we then utilized forward predictions of population dynamics to investigate different scenarios of range recolonization.
