Eta Carinae could be as large as 180 times the radius of the Sun, and its surface temperature is 36,000-40,000 Kelvin. Just for comparison, 40,000 Kelvin is about 72,000 degrees F. So it's the blue hypergiants, like Eta Carinae, which are probably the hottest stars in the Universe.

The pentose phosphate pathway (PPP) is localized to the cytosol.
DIA [1.3K]

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>

If a compound has a molar mass of 180 g/mol and its empirical formula is CH2O, what is its molecular formula? CH2O C2H4O2 C6H12O
irinina [24]

Its molecular formula : C₆H₁₂O₆

<h3>Further explanation  </h3>

The empirical formula(EF) is the smallest comparison of atoms of compound forming elements.  

A molecular formula(MF) is a formula that shows the number of atomic elements that make up a compound.  

(EF) n = MF

its empirical formula is CH₂O

CH₂O : 12+2+16=30

\tt [30]n=180\rightarrow n=6\\\\(CH_2O]_6=C_6H_{12}O_6
