Below are the questions for the exam with the choices of answers:
Question #1
A the number of covalent bonds a molecule can form
B Known as ATP, is an important source of energy for cellular processes
C a substance that increases the hydrogen ion concentration of a solution
Question #2
A This functional group contain sugar with ketone group is called a ketose; the one with aldehyde is called an aldose.
