Bonds
True or False: Amino acids are connected by glycosidic bonds.
False; peptide bonds
What is entropy?
the amount of disorder in a thermodynamic system.
How do proteins know how to fold correctly?
proteins know how to fold correctly because they are informed by the sequence of amino acids.
True or False: Prokaryotes have 1 copy of DNA, while Eukaryotes have 2 copies of DNA.
True
Carbon has 6 protons and 6 electrons. How many grams is one mol of carbon?
6+6=12 grams
What are the three types of bonds that make up Van der Waal Forces?
Hydrogen Bond, Dipole-Dipole, and London Dispersion
True or False: The 1st Law of Thermodynamics states that energy can be created, but it cannot be destroyed.
False; energy cannot be created or destroyed
Amyloid sheets can form...., which have a (negative/positive) impact on protein folding.
Prions; negative
How do prokaryotes and eukaryotes reproduce? Give examples of each.
Prokaryotes reproduce through asexual reproduction. An example of this would be binary fission. Eukaryotes reproduce through sexual reproduction. An example of this would be mitosis and meiosis.
Why are moles important?
They represent the number of particles that are available to participate in a chemical reaction.
True or False: Ionic bonds most commonly form between a metal and nonmetal.
True
What does the 2nd Law of Thermodynamics state?
Entropy does not decrease in thermodynamic systems.
Which of the following is not a type of protein:
a) Enzymes
b) Nucleotides
c) Transcription Factors
d) Receptors (ex: insulin receptor)
What are two things that both prokaryotes and eukaryotes have?
They both have cell membranes and they both have DNA.
What is a valence electron?
An electron on the outermost ring.
Double bonds are
a) shorter than single bonds, but don't share more electrons than single bonds.
b) longer than single bonds and share more electrons than single bonds.
c) shorter than single bonds and share more electrons than single bonds.
d) longer than single bonds, but don't share more electrons than single bonds.
c) shorter than single bonds and share more electrons than single bonds.
How do cells obey the laws of thermodynamics?
Cells obey it's because they are organized, and cells release heat.
Why are chaperones important?
Chaperones are important because they assist with protein folding.
True or False: Prokaryotes are bigger in size compared to eukaryotes, and do not have a nucleus.
False; smaller in size
If an atom is not stable, they can form a ... bond, where electrons are shared, or they can form a ... bond, where electrons are stolen.
covalent-share
ionic-steal
