Answer:

The Answer is,  B, C, And E. I just took it on USATESTPREP.

B) G3P can be used to form the backbone of triglycerides. Glycerol combines with fatty acid tails to form lipids.

C) Two G3P molecules can be combined through anabolic processes to form glucose, a six-carbon sugar required by cells.

E) G3P can be used in to synthesize amino acids, which contain a central carbon, a carboxylic acid group, and a variable R group. These amino acids can then combine to form proteins.

Which food is at a temperature that allows bacteria to grow well ? A) a roast at 125•F (52•c) B) hamburgers at 165•f (74•c) C) p
Lilit [14]

The correct answer is A) A roast at 125°F (52°C)

Explanation:

In general terms, bacteria thrive at warm temperatures; this means bacterial growth is lower at extremely hot/cold temperatures, but it is higher at warm or medium temperatures. Indeed, the ideal temperature for bacteria to develop and reproduce is between 4° C and 60°C. This implies from the options given the roast at 52°C represents an ideal temperature for the growth of bacteria. Also, other options include temperatures above 60°C, and therefore do not allow bacteria to grow well.

Which statement correctly distinguishes the roles of protein kinases and protein phosphatases in signal transduction pathways?
vesna_86 [32]

Answer:

A) Protein kinases activate enzymes by phosphorylating or adding phosphate groups to them. Protein phosphatases dephosphorylate or remove phosphate groups from enzymes, including protein kinases.

Explanation:

Protein kinases are enzymes that have the ability to modulate other enzymes (or some other proteins) by adding the phosphate group. This is known as phosphorilation process. As a result of structural change, protein can change its activity (phosphorilation usually increase the activity).

Phosphatases are enzymes with opposite function, they remove phosphate group from the protein causing different effect.
