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
