PCB3023 Exam 1, cell bio test 1 FAU
Theisen, CH.1: Cells and Genome
Practice Questions and Answers

proteins are able to bind to which of the following types of
biological molecules - Answer✔️✔️-- amino acids, sugars,
nucleotides, lipids, are basis for most reactions in cells. All proteins
are able to bind to one or more molecules, often other proteins and
bound substances such as ligands or substrates.

in cells the strongest chemical interaction is? - Answer✔️✔️--
covalent bonds ; covalent bonds are strong, stable, long-lasting.

hydrogen bonds are... - Answer✔️✔️-polar covalent, individually
weak, but many bonds together can be strong.

ionic bonds are... - Answer✔️✔️-strong and pliable but can easily be
disrupted by polar solvents (eg. water)

van der waals forces are... - Answer✔️✔️-individually very weak

the majority of biological catalyst are made from... - Answer✔️✔️--
amino acids

In the A, B, C class of protein transport pump. The conformation
changes that lead to translocation of the transporter substance are

caused by... - Answer✔️✔️-- repeated cycles of ATP binding and
hydrolysis

True regarding prokaryotic cells? - Answer✔️✔️-- has a cell wall

- reproduce by binary fission

- do not exist as true...

- utilize double strands for hereditary material

- do NOT package their DNA so they do NOT need histones

Evolution of the nucleus in eukaryotic organisms has allowed... -
Answer✔️✔️-- Segregation of DNA from other cellular processes

- Increase the size of the DNA molecule

When a carbohydrate is oxidized it loses both ____ and ____. -
Answer✔️✔️-- electrons and energy ; Oxidation is the loss of electrons
and energy. The atom is left with a more POSITIVE charge.

what is meant by high specificity between molecules? - Answer✔️✔️--
highly complementary physical shape

- highly complementary electro chemical properties

The histones used to package newly replicated DNA - Answer✔️✔️--
added to DNA as it is emerging from the replication machinery

mutations within DNA coding regions... - Answer✔️✔️-- usually
results to deleterious changes in protein structure



DNA coding regions have important information, any mutations on
these regions are most of the time negative (bad), so it will not be
beneficial.

Entropy is the measure of... - Answer✔️✔️-- the amount of disorder
in a system

a protein secondary structure is maintained by - Answer✔️✔️--
hydrogen bonds



hydrogen bonds are the bonds between atoms

binding of a ligand to a specific enzyme binding site... - Answer✔️✔️--
involves numerous weak noncovalent bonds



it is not a permanent binding, so it CANNOT be covalent, it has to
be a weak bond in order for it to be able to break or go back to its
original form.

Chemical analysis of DNA will reveal the following... - Answer✔️✔️--
Concentration of Purines equals concentration of Pyrimidines

Because its circular, replication of prokaryotic DNA does NOT
require... - Answer✔️✔️-- Telomerase function



Telomerase is used to stabilize the ends of Eukaryotic chromosomes
which are linear. Since prokaryotic DNA is not linear, it does NOT
need telomerase to stabilize its ends.

Flipping out refers to... - Answer✔️✔️-- The temporary separation of a
base from its compliment to allow close inspection.

activation energy is a property of... - Answer✔️✔️-- all types of
chemical reactions



It is NOT the energy required to push a reaction in an unfavorable
direction.

Universal features of all cells... - Answer✔️✔️-- take up matter from
their surroundings

- store hereditary information

- use RNA to direct protein synthesis

- all cells use DNA

- all cells replicate their DNA
