Answer:Heat is a type of ENERGY. When absorbed by a substance, heat causes inter-particle bonds to weaken and break which leads to a change of state (solid to liquid for example). Heat causing a phase change is NOT sufficient to cause an increase in temperature.
Explanation:
<span>
As a liquid is heated, its vapor pressure increases until the vapor pressure
equals the pressure of the gas above it.
Bubbles of vaporized liquid (i.e., gas) form within the bulk liquid and
then rise to the surface where they burst and release the gas. (At
the boiling temperature the vapor inside a bubble has enough pressure to
keep the bubble from collapsing.)
In order to form vapor, the molecules of the liquid must overcome the forces
of attraction between them.<span>
The temperature of a boiling liquid remains constant, even when more heat
is add.</span></span>
Answer: The pentose phosphate pathway (PPP) is localized to the cytosol because fatty acid synthesis uses the NADPH generated by the PPP.
Explanation:
The pentose phosphate pathway is mainly catabolic and provides an alternative glucose oxidizing pathway for the generation of NADPH that is required for reductive biosynthetic reactions such as those of cholesterol biosynthesis, bile acid synthesis, steroid hormone biosynthesis, and fatty acid synthesis.
Fatty acid biosynthesis occurs in the cytosol and requires the reducing equivalent NADPH in large amounts. <em>The main source of generating NADPH in animal cells, the pentose phosphate pathway is therefore, localized in the cytosol in order to furnish a strongly reducing environment for fatty acid biosynthesis to proceed.</em>
