BIOD 152 LAB 2 SPECIAL SENSES EXAM
EXAMINATION TEST 2026 COMPLETE
QUESTIONS AND SOLUTIONS GRADED A+
◉ What are the four major differences btw DNA and RNA? Answer:
1. DNA contains deoxyribose - RNA is ribose
2. DNA: thymine
RNA: uracil
3. DNA: double stranded helix
RNA: single strand
◉ DNA is often described as a coiled ladder. In this description, what
two parts of a DNA nucleotide form the uprights? What part forms
the rungs? Answer: The uprights are the sugar phosphate backbone,
and the rungs are the bases.
◉ Explain the 2 differences btw hydrolysis and dehydration
condensation. Answer: During dehydration condensation
biomacromolecules are synthesized by joining building block
monomers. A water molecule is lost and energy is used.
Biomacromolecules are broken down into monomers during
hydrolysis when a water molecule is added and energy is released.
,◉ Tell whether each of the following is carbohydrate, lipid, protein,
or nucleic acid. Then explain the use of each.
GLUCOSE Answer: Carbohydrate; used as fuel, is referred to as blood
sugar in humans and animals
◉ Tell whether each of the following is carbohydrate, lipid, protein,
or nucleic acid. Then explain the use of each.
Starch Answer: Carbohydrate; the form in which plants store glucose
◉ Tell whether each of the following is carbohydrate, lipid, protein,
or nucleic acid. Then explain the use of each.
Cellulose Answer: Carbohydrate; woody tissue in plants and trees,
indigestible fiber
◉ Tell whether each of the following is carbohydrate, lipid, protein,
or nucleic acid. Then explain the use of each.
Triglyceride Answer: Lipid; the major form of fuel storage that when
broken down produces twice as much energy per gram than
carbohydrates
,◉ Tell whether each of the following is carbohydrate, lipid, protein,
or nucleic acid. Then explain the use of each.
Phopholipid Answer: Lipid; the major constituent of cell membranes
◉ Tell whether each of the following is carbohydrate, lipid, protein,
or nucleic acid. Then explain the use of each.
Hemoglobin Answer: Protein; carries oxygen in the blood
◉ Tell whether each of the following is carbohydrate, lipid, protein,
or nucleic acid. Then explain the use of each.
DNA Answer: Nucleic Acid; contains genetic material of cells
◉ Tell whether each of the following is carbohydrate, lipid, protein,
or nucleic acid. Then explain the use of each.
RNA Answer: Nucleic Acid; part of the protein-synthesizing
operation of the cell
◉ Tell whether each of the following is carbohydrate, lipid, protein,
or nucleic acid. Then explain the use of each.
, Cholesterol Answer: Lipid; component of animal cell membranes
that, when in excess, can form plaque on artery walls
◉ Tell whether each of the following is carbohydrate, lipid, protein,
or nucleic acid. Then explain the use of each.
ATP Answer: Nucleic Acid; releases energy through the breaking of
high-energy phosphate bond
◉ Tell whether each of the following is carbohydrate, lipid, protein,
or nucleic acid. Then explain the use of each.
Glycogen Answer: Carbohydrate; the form in which animals and
humans store glucose
◉ Tell whether each of the following is carbohydrate, lipid, protein,
or nucleic acid. Then explain the use of each.
Insulin Answer: Protein; a hormone
◉ Why are proteins so often used to build structures? Answer:
Because they are "structurally sophisticated". They are strong, yet
flexible and incredibly diverse.
