During reduction, 3-PGA reacts with ATP and NADPH. What does ATP contribute to the reaction? A. carbon B. hydrogen ions C. electrons D. phosphate group

QUESTION POSTED AT 06/12/2019 - 12:34 PM

Answered by admin AT 06/12/2019 - 12:34 PM

D. phosphate group

ATP usually releases energy by breaking down the weak phosphate cell present.  The energy released due to the breaking down of the phosphate cell is then utilized. The ATP is converted to ADP. Whenever a cell feels the necessity for energy it releases a phosphate to gather the energy. It is an automatic and ongoing process. The weak bond between the second and the third phosphate is always targeted for turning ATP to ADP. This is the reason ATP is considered the main energy currency for the cell.

Henry eats rice for lunch, which contains starch. Which enzyme catalyzes the reaction that takes place and which product is the result of this reaction? Amylase catalyzes the reaction; glucose is the product Pepsin catalyzes the reaction; lactase is the product Lactate dehydrogenase catalyzes the reaction; lactate is the product

Answer:

Amylase catalyzes the reaction; glucose is the product

Explanation:

In the process of digestion, polysaccharides like starch are broken down into monosaccharides before being absorbed. Digestion of starch is catalysed by amylase enzymes which are salivary amylase and pancreatic amylase. Salivary amylase begins digestion of starch inside mouth during chewing process. The digestion is further carried out by pancreatic amylase in small intestine. The starch is hydrolysed in digestion process and the products are glucose, maltose, maltotriose and α-dextrins. Disaccharides like maltose are further converted into monosaccharides by enzymes like maltase which are present in brush border of small intestinal cells.

Select all that apply Smaller groupings within a species are called _____. varieties/ races / breeds/ mongrels

Answer:

The correct answers would be varieties, races, and breeds.

In binomial nomenclature, variety refers to the taxonomic rank present below the species and subspecies. It is mainly used in the nomenclature of plants.

In a taxonomic hierarchy, race refers to the informal rank below subspecies. The race includes a genetically distinct group of organisms within the same species.

Breeds refer to the different varieties of same species. These organisms similar to appearance, behavior, and other characteristics. It is mainly used for domesticated animals. For example, Rottweiler and German Shepherd are two different breeds of dog.

The level of carbon dioxide was measured in a garden and on a city road. Where do you think the carbon dioxide level will be higher and why? A. The carbon dioxide level will be same at both places because the amount of carbon dioxide at all places on the earth is the same. B. The carbon dioxide level in the city will be higher because the exhaust gases from vehicles release carbon dioxide and there are not many trees to utilize it. C. The carbon dioxide level in the garden will be higher because of the many plants present which are constantly releasing carbon dioxide by photosynthesis

The answer is B. The carbon dioxide level in the city will be higher because the exhaust gases from vehicles release carbon dioxide and there are not many trees to utilize it.

There are more plants in the garden than on the city road. It is known that plants absorb carbon dioxide and together with water in the process of photosynthesis produce their own food and release oxygen. Vehicles release carbon dioxide to the atmosphere. So, if there are enough plants, the amount of carbon dioxide can be absorbed by the plants. Since there are not many plants on the city road, it is expected there will be higher level of carbon dioxide than in the plant-rich garden.

Which of the following do Meiosis and Mitosis have in common? A. They are considered to be reduction divisions as the processes result in additional cells. B. The genetic composition of the daughter cells is identical to the parent cell. C. In both processes the DNA replicates during interphase.

Hello:)

Meiosis is the production of four gametes (sex cells). This process results in four gametes, which each have half the number of chromosomes than the original cell. So that crosses out answer B. Mitosis is the production of two genetically identical cells. In Meiosis, DNA does "crossing over" where the strands cross over and trade bits of genetic information.
Anyways, I would choose option C, because in interphase in mitosis AND meiosis, that is when the DNA replicates

Which statement explains the difference between multiple alleles and polygenic inheritance? A) Multiple allele means more than one gene contributes to the phenotype and polygenic inheritance means more than two forms of the same gene in the population. B) Multiple allele means more than two forms of the same gene in the population and polygenic inheritance means more than one gene contributes to the phenotype of a trait. C)Multiple allele means more than two forms of different genes in the population and polygenic inheritance means one gene contributes to many phenotypic characters.

 The answer is B) Multiple allele means more than two forms of the same gene in the population and polygenic inheritance means more than one gene contributes to the phenotype of a trait.

An allele is one of two or more alternative forms of a gene. So, multiple allele means more than two forms of the same gene in the population. 
Polygenic inheritance is responsible for traits that are controlled by two or more genes. The name itself explains the meaning: poly means many, so literally it means many genes.
