BIO 1201 GREGG EXAM 1 2026 ECOLOGY
FUNDAMENTALS WORKBOOK SOLVED
QUESTIONS COMPILATION
◉ In any aqueous solution @25C the product of H+ and OH-
concentrations is constant @.
Answer: 10^-14
◉ [H+][OH-]=.
Answer: 10^-14
◉ Buffers.
Answer: Allow biological fluids to maintain relatively constant
despite additions of acids and bases
◉ hydroxyl group (-OH).
Answer: Polar due to electronegative oxygen. Forms hydrogen bonds
with water.
Compound name: Alcohol
◉ Carbonyl group (C=O).
,Answer: Polar. Sugars with ketone groups called ketones (w/in C
skeleton) aldehyde called Al doses (end of C skeleton)
◉ Carboxyl group (-COOH).
Answer: Polar. acts as an acid (can donate H+) because the covalent
bond between oxygen and hydrogen is so polar. Compound Name:
Carboxylic acid, or organic acid
◉ Amino group (-NH2).
Answer: Polar. acts as a base; can pick up an H+ from the
surrounding solution (water, in living organisms). Compound name:
amine
◉ sulfhydryl group (-SH).
Answer: Polar. Two —SH groups can react, forming a "cross-link"
that helps stabilize
protein structure. Compound name: Thiol
◉ Phosphate Group (—OPO32).
Answer: Polar. Contributes negative charge. When attached, confers
on a molecule the ability
to react with water, releasing energy. Compound name: Organic
phosphate
, ◉ Methyl group (-CH3).
Answer: Nonpolar. Affects the expression of genes. Affects the shape
and function of
sex hormones. Compound name: Methylated compound
◉ ATP (adenosine triphosphate).
Answer: Composed of a sugar ribose, nitrogenous base adenine, and
a chain of three phosphate groups bonded to it.
◉ Hydrocarbons.
Answer: organic molecules consisting of only carbon and hydrogen
◉ Isomers.
Answer: Compounds with the same formula but different structures.
◉ structural isomers.
Answer: Differ in arrangement of atoms.
◉ Enantiomers.
Answer: isomers that are mirror images of each other
◉ cis-trans isomers (geometric isomers).
