Answer:
It is not usually a component of eukaryotic membranes.
Explanation:
Cholesterol is responsible for modulating the fluidity of the cell membranes of eukaryotes.
It is produced in most animal cells, and its formation is substantially active in <u>liver</u> cells, where bile acids are synthesized from cholesterol.
In addition, cholesterol is the precursor of steroid hormones such as progesterone, testosterone, estradiol and cortisol.
Cholesterol (like other lipids) is <u>amphipathic</u>, meaning it has a polar head (hydrophilic) and an apolar tail (hydrophobic).
Given the above, it can be concluded that the false statement is "it is not usually a component of eukaryotic membranes".
Answer:
Glucose - a simple sugar which is an important energy source in living organisms and is a component of many carbohydrates.
Explanation:
The energy of the earth's interior is known as the earth's internal energy. This powers the internal processes within the earth.
- This energy is very important in the rock cycle for the formation of both igneous and metamorphic rock.
- The energy is a product of frictional heating, radioactive decay of isotopes and heat that acreted when the earth was forming.
- The internal engine is responsible for mantle convection in which molten rock from within the earth rises to the surface and denser slabs of the lithosphere falls back within.
- It is responsible for the heating of sedimentary rocks to form metamorphic rocks around subduction zones.
