Hydrophobic is water fearing so this will be the inside or between.

Hydrophilic is water loving so this will be in direct contact with the water so it should go at two places.

The plasma membrane is AMPHIPATHIC (important word) meaning it was two sides a water loving and water fearing side. The circle is polar meaning is wants to make contact with water and the middle is non polar meaning it doesn’t want to be near water

What is true about the absorption and storage of fat-soluble versus water-soluble vitamins in the body?
rodikova [14]
The right answer is "<span>fat soluble are stored in the liver and fatty tissue ...".

Lipids are essentially stored as fatty acids in the cytoplasm of adipocytes. All of these cells form adipose tissue, commonly called "fat".These reserves are much larger in quantity than the reserves in the form of glycogen, in the human body.

"<span>water-soluble vitamins can build to toxic levels ..." is false, hydrosoluble vitamins are rarely toxic, even at high concentrations, and even if they are toxic (which is very rare) is it not due to their circulation in the bloodstream, it is due to their accumulation in cells.</span>

Indicate whether each of the following statements is true of depurination (DP), deamination (DA), or pyrimidine dimer formation
solniwko [45]

Answer:

- This process is caused by spontaneous hydrolysis of a glycosidic bond: depurination and deamination

- This process is induced by ultraviolet light:  pyrimidine dimer formation

- This can happen to guanine but not to cytosine: depurination

- This can happen to thymine but not to adenine:  pyrimidine dimer formation

- This can happen to thymine but not to cytosine: none

- Repair involves a DNA glycosylase: deamination

- Repair involves an endonuclease: depurination, deamination and  pyrimidine dimer formation

- Repair involves DNA ligase: depurination, deamination and  pyrimidine dimer formation

-  Repair depends on the existence of separate copies of the genetic information in the two strands of the double helix: depurination, deamination and  pyrimidine dimer formation

- Repair depends on cleavage of both strands of the double helix: none

Explanation:

Depurination is the loss of purine bases (either adenine or guanine), while deamination refers to the removal of an amino group. During depurination, a β-N-glycosidic bond is cleaved by hydrolysis and a nucleic base is released (either adenine or guanine). All DNA bases may undergo deamination, except thymine (since thymine does not have an amino group). The ultraviolet (UV) radiation can cause thymine or cytosine to form dimers (e.g., pyrimidine dimers), being thymine dimers the most common lesion when DNA is exposed to UV light. Pyrimidine dimers may be repaired by different excision mechanisms, e.g., nucleotide excision repair, where the recognition of the DNA damage leads to the removal of the DNA fragment containing the lesion. DNA glycosylases are enzymes involved in the mechanism of base excision, these enzymes recognize and remove damaged bases by hydrolysis of the glycosidic bond, producing an abasic (apurinic and apyrimidinic) site. A DNA ligase enzyme covalently joins two DNA molecules by forming a phosphodiester bond, which is required during these processes.
