Question

1. Which of the following is true regarding saturated fatty acids?

they contain one carbon double bond

they contain multiple carbon double bonds

they contain no carbon double bonds

they are the building blocks of nucleic acids

2. In anaerobic respiration (fermentation), one glucose can yeild 2 ATP's, and lactic acid is a by-product.

true or false

3. Which of the following is true regarding saturated fatty acids?

they contain multiple carbon double bonds

they contain one carbon double bond

they contain no carbon double bond

they are building blocks on nucleic acid

4. Which of the following is most important in determining what type of chemical bonds will form between atoms?

protons

neutrons

valence shell electrons

all of the above

5. Which of the following explains why water has a high surface tension, heat capacity, and heat of vaporization?

adjacent water molecules readily form covalent bonds with each other

water molecules are polar covalent thus form hydrogen bonds with each other

the non polarity of water

water molecules form ionic bonds with adjacent water molecules

Answer 1

1.Saturated fatty acids has no carbon double bonds is the right answer.It has only single covalent bonds.Thats why it is known as saturated fatty acids

2.It is true,In anaerobic respiration one glucose can yield 2 ATP and it's by product is lactic acid.

3.Saturated fatty acids has no carbon double bond is the right answer.

4.valance shell electrons determines the type of chemical bond.

Proton is the subatomic particle also it has a positive charge.

Neutron is the neutral subatomic particle.Protons and the neutrons together form the nucleus which is situated at the center of an atom.

5.Water molecules are polar covalent thus form hydrogen bonds with each other.

In water molecule the oxygen atom spends more time with the electrons so the hydrogen has negative charge.Thus it hydrogen bonds with each other and has high surface tenstion,heat capacity and heat of vaporization.
