  1. Which class of biomolecule includes enzymes?

    Answer: Proteins

    Enzymes are proteins that catalyze biochemical reactions.

  2. What is the general formula for a saturated alkane?

    Answer: CnH2n+2

    Alkanes follow CnH2n+2 because they contain only single bonds.

  3. Markovnikov's rule predicts the product of:

    Answer: Addition of HX to an alkene

    Markovnikov's rule states H adds to the carbon with more hydrogens during HX addition to alkenes.

  4. Which monosaccharide is the primary fuel for cellular respiration?

    Answer: Glucose

    Glucose is the main sugar oxidized to release energy in cells.

  5. An sp3 hybridized carbon has what bond angle?

    Answer: 109.5 degrees

    sp3 hybridization gives tetrahedral geometry with 109.5 degree angles.

  6. Which type of lipid is the main component of cell membranes?

    Answer: Phospholipids

    Phospholipids form the bilayer that makes up cell membranes.

  7. What product forms when a carboxylic acid reacts with an alcohol?
