BSC2010 Exam 1 questions with verified answers
"alpha Glucose" Ans✓✓✓ -Carbon 1 below the ring
-helical structure
-forms branches
-bond/break for efficient energy
ex. Starch, Glycogen
"Beta Glucose" Ans✓✓✓ -Carbon 1 above the ring
-no helices
-non branching
-IM weak interactions form microfibrils
3 Monosaccharides and 3 Disaccharides commonly found in our diet?
Ans✓✓✓ Monosaccharides
1. Glucose
2. Fructose
3. Galactose
Disaccharides:
1. Maltose = Glucose + Glucose
,2. Sucrose = Glucose + Fructose
3. Lactose = Glucose + Galactose
3 Subatomic Particles: location, mass, and charge. Ans✓✓✓ Electron-
e- cloud, mass negligable, -1 charge
Proton- Nucleus, 1.7 x 10^-24 = 1 D, +1 Charge
Neutron- Nucleus, 1.7 x 10^-24 = 1 D, no charge
8 Characteristics of Life as it is known on Earth Ans✓✓✓ Complex /
Ordered
-Regulated
-Responsive
-Grows
Well- Adapted
Reproduces
Uses Energy
Carries Instructions (DNA)
Aldose Ans✓✓✓ Monomer with carbonyl group at END of Carbon
backbone
, Are all hydrophilic substances soluble? Ans✓✓✓ No, a substance can
be hydrophilic (ionic and polar) and not be soluble bc it is too large.
Macromolecule (>1000D)
i.e. cotton towel
Are biological molecules typically polar or nonpolar? How do they bond
with respect to one another? Ans✓✓✓ POLAR- usually bear partial and
full charges - dictate structure and function!
C-O, H-O, C-N, H-N: Polar Covalent due to non equal sharing (DNA +
Proteins)
Atom Ans✓✓✓ Fundamental unit of matter, smallest unit of an
element
Atomic Number Ans✓✓✓ # protons
Atomic Weight Ans✓✓✓ Mass of atom (amu)
Basic Structure of a Monosaccharide, structure of biological
monosaccharides: Ans✓✓✓ Monosaccharides' basic form is a chain
following (CH2O)n
-a carbonyl group and many hydroxyl groups
Biological Monosaccharides form rings in aqueous environments
