Question

a phospholipid differs structurally from a triglyceride in that it has three phosphate groups attached to the glycerol molecule rather than three fatty acid chains.
a true
b false
question 12
the first electron shell of an atom can hold a maximum of
a 1 electron.
b 2 electrons.
c 4 electrons.
d 8 electrons.

Explanation:

First Question (Phospholipid vs Triglyceride)

A triglyceride has three fatty acid chains attached to glycerol. A phospholipid has two fatty acid chains and one phosphate - containing group attached to glycerol, not three phosphate groups. So the statement is false.

According to the electron shell rules, the first electron shell (n = 1) of an atom can hold a maximum of 2 electrons. The formula for the maximum number of electrons in a shell is $2n^{2}$, for n = 1, $2\times(1)^{2}=2$.

Answer:

B. False

Second Question (Electron Shell Capacity)
