Hundreds of amino acids are bonded together to form a polypeptide chain. This is an example of a what type of reaction?
The law expresses that energy can be transformed, i.e. changed from one form to another, but cannot be created or destroyed.
What is the 1st law of thermodynamics?
every energy transfer or transformation increases the entropy of the universe. (we are destroying the planet by existing hehe)
What is the 2nd law of thermodynamics?
degradation or breakdown reactions, which result in the release of energy. The energy release can be used to directly to perform cellular work.
Define Catabolic pathways:
reactions that proceed with a net release of energy. note the products of the reaction contain less energy than reactants.
reactions that proceed with a net input of energy. note: the reaction must get energy from their surroundings. The products of the reaction contain more energy than the reactants.
a reaction that can occur without the input of energy. This term does not imply that the reaction occurs quickly or instantaneously. e.g. Rusting of metal is a spontaneous process but occurs over a long period of time.
Define spontaneous reactions:
Anabolic: builds, need energy input, energy can be stored.
Catabolic: breakdown, will export/release energy, can release energy
anabolic vs catabolic
Oxidation Reduction reaction aka REDOX reaction
How does a catabolic pathway such as cellular respiration yield energy? (hint: it involves electrons)
