NVCC BIO 101 EXAM 2 QUESTIONS AND ALL ANSWERS
CORRECT
The entirety of an organism's chemical reactions is known as metabolism.
Metabolic pathway: ANSWER starts with a particular molecule that is
changed in a number of predetermined stages to produce a particular product.
Catabolic pathway: ANSWER releases energy by disassembling complicated
molecules into simpler ones.
Anabolic pathways: ANSWER uses energy to transform simpler molecules
into complex ones.
Amino acids, which are simpler molecules, are used to make proteins.
The study of how energy moves through living things is known as
bioenergetics.
Energy is the ability to bring about change.
Kinetic energy is the ANSWER to motion's energy.
Thermal energy is the kinetic energy that results from atoms or molecules
moving randomly.
Heat is the transfer of thermal energy from one item to another.
Potential energy is the energy that matter contains due to its structure or
position.
Chemical energy is the potential energy that can be released during a chemical
process.
The study of energy changes that take place in a group of materials is known as
thermodynamics.
The first law of thermodynamics states that although energy cannot be
generated or destroyed, it may be transported and altered.
Also known as the conservation of energy concept
, The second law of thermodynamics states that every change or transfer of
energy raises the universe's entropy.
Entropy is a measure of randomness or molecular disorder.
The term "disorder" is used by physicists to characterise the number of energy
levels and the dispersion of energy in a system.
Chemical reactions: Endergonic ("energy in") is the ANSWER
Exergonic (or "energy out")
Coupling of energy
Endergonic: A chemical reaction that needs energy to continue
produces a product with a lot of potential energy.
Reactabr molecules with comparatively low potential energy are the starting
point, whereas the final products have higher chemical energy.
Exergonic reactions are chemical processes that release energy.
These processes liberate the energy contained in the reactants' covalent bonds.
Burning wood releases glucose's energy as light and heat.
Utilising an exergonic process to propel an endergonic one is known as energy
coupling.
Adenosine triphosphate, or ATP, is the primary energy source that cells use for
the majority of their functions.
consists of a chain of three phosphate groups, adenine, a nitrous base, and
ribose, a sugar.
In addition to producing ATP (adenosine diphosphate) and inorganic phosphate,
ATP hydrolysis releases energy.
The energy released is not from the phosphate bonds themselves, but rather
from the chemical transition to a lower free energy state.
An enzyme is a macromolecule that acts as a catalyst, a chemical agent that
modifies a reaction's rate without being consumed by it.
The majority of enzyme names conclude with -ase.
A catalyst is a material that increases the rate of a chemical process.
The energy required to initiate a reaction by rupturing the bonds between the
reactant molecules is known as activation energy.
Three primary types of work are performed by a cell: chemical, transport, and
