Which of the following is true of anabolic reactions? View Available Hint(s) Which of the following is true of anabolic reaction
puteri [66]

Answer:

Anabolic reactions use ATP and small substrates as building blocks to synthesize larger molecules.

Explanation:

Anabolic reactions are part of metabolic pathways that occur inside the living cells. Anabolic reactions always form complex molecules from simpler substances. The formation of glucose from relatively simpler CO2 and H2O during the Calvin cycle is an example of the anabolic pathway. During anabolic pathways, the metabolic energy of ATP hydrolysis drives the endergonic reactions. Therefore, anabolic reactions consume ATP. Calvin cycle uses the ATP produced during light reactions of photosynthesis.

Which of the following would NOT be considered a reemerging disease?
nignag [31]

Answer:

Option D, West Nile virus fever/encephalitis

Explanation:

A re-emerging disease is one which after a long span of time has re-emerged again as the microbes causing such diseases have become resistant to the    existing drugs.

Here tuberculosis , malaria and gonorrhea  are the re-emerging disease as the microbes causing these diseases have become resistant to the available drugs and thus there is a need to produce medicines that  could fight with the re-emerged multi drug resistant tuberculosis , Malaria and gonorrhea

Hence, option D is correct.

proteins need to be denatured using an anionic detergent such as sds before gel electrophoresis because: select all that apply.
grandymaker [24]

The majority of proteins contain a uniform positive charge, and a uniform neutral charge, and most proteins have intricate three-dimensional structures that might affect how well they travel through the gel electrophoresis. For these reasons, proteins need to be denatured. Here, the right answers are A, B, and D.

Protein separation is accomplished using a molecular technique called sodium dodecyl sulfate-polyacrylamide gel electrophoresis, which operates in the proximity of an electric charge. Proteins are separated using SDS-PAGE according to their electrophoretic mobility. Protein charge, shape, and structure all affect electrophoretic mobility.

To proceed in the direction of the positive terminal, the protein molecules need to have a constant negative charge (anode). The overall charge of a protein is determined by the amino acid content of the protein as well as the charge of the individual amino acids.

Thus, depending on the total makeup of amino acids, the charge may change. Depending on the ratio of different amino acids, the total charge of the proteins can be positive, negative, or neutral. The SDS treatment gives the proteins a consistent, negative charge. Then, according to size, the negatively charged amino acids flow toward the positive terminal.

Complete question:

Proteins need to be denatured using an anionic detergent such as SDS before gel electrophoresis because: Select all that apply.

A - most proteins have a uniform positive charge

B - most proteins have complex three-dimensional structures that can impact their movement through the gel

C - the overall charge of a protein depends on the amino acid composition of the protein and can vary greatly

D - most proteins have a uniform neutral charge
