Which of the following is NOT a mechanism used to temporally regulate the activity of maturation-promoting factor (MPF)?

Biology

Answer:

C. glycosylation

Explanation:

The maturation-promoting factor (MPF) is a cell cycle checkpoint that stimulates the passage from G2 (prophase) to M phase (metaphase). MPF also determines that DNA replication during the S (synthesis) phase did not produce any mutations. MPF is inactivated by kinase phosphorylation and activated by specific phosphatases capable of dephosphorylating this protein. On the other hand, glycosylation is a posttranslational modification where a carbohydrate (i.e., a glycan) is added to a functional group of another molecule. Many proteins undergo glycosylation, thereby playing a critical role in regulating protein function.

kicyunya [14]

Answer:

<em><u>H1: false, the observations of the molecules do not support the hypothesis...</u></em>

Explanation:

The cell membrane is comprised of a phospholipid bilayer, proteins, and cholesterol. These components help the membrane to maintain its selective permeability and concentration of solutes and water.

The lipid molecules have polar hydrophilic heads and hydrophobic tails. These only readily allow for the movement of small non polar molecules. Other substances, like charged ions and large molecules require transport proteins to move in and out of the cell. Hypothesis: H+ is small and should be able to move freely through the membrane, While glucose is large and cannot move freely

  • Observing H+, despite being very small these cannot easily pass through the membrane. They require transport proteins called channels for their free movement or passive movement across the membrane.
  • For glucose, these molecules pass through specialized channels in facilitated diffusion. They move down their concentration gradient into the cell. To move out of the cell against its concentration gradient glucose requires ATP for active transport.
  • Cortisol, is a large steroid hormone, taken into the cell by simple diffusion across the lipid membrane, down its concentration gradient.

Answer:

Carbohydrates

Explanation:

Like most classes of biological molecules, carbohydrates occur as both monomers and polymers. Small carbohydrates are called sugars, which commonly include monosaccharides (single sugars) and some disaccharides (two sugars linked together). Larger carbohydrates are called polysaccharides (many sugars linked together).
