Unit 2- Metabolic Processes Flashcards
2nd Law of thermodynamics
In every transfer, some of the useful energy in the system becomes unstable
1st Law of thermodynamics
Energy cannot be created or destroyed, just converted
Hydrolysis
A chemical reaction where water is used as a reactant to split a larger molecule into smaller subunits.
Catabolic reactions
A complex substance is broken down into something less complex and this releases energy
Anabolic reactions
A complex substance is built from something less complex and this energy must be put into the reaction to synthesize the larger ones
Entropy
An increase of disorder in a system
Free energy
Energy that can do useful work. Also called Gibbs free energy
Enthalpy
The amount of heat energy exchanged between the system and surroundings during a process provided the temperature and pressure are kept constant.
Photosynthesis 1
A collection of pigment proteins that includes chlorophyll a and absorbs light at the 700nm wavelength
Photosynthesis 2
A collection of pigment proteins that includes chlorophyll a and absorbs light at the 680nm wavelength, where the splitting of water molecules occur
The Calvin cycle
Takes place in the stroma of the chloroplast.
Also known as dark reactions.
Calvin cycle
Carbon fixation
Reduction
Regeneration
Why during except use we develop soreness in our muscles?
Your cells will demand more ATP than the amount of O2 your body can produce. Glycolysis will happen rapidly and this causes excess pyruvate. This pyruvate turns into lactic acid. The la tic acid rests in your muscles. This process is called lactic fermentation.
Spontaneous change
A change that will once begin, continues on its own and does not require a continuous energy input, DeltaG is negative
Non-spontaneous change
A change that cannot occur without continuous energy input, DeltaG is positive
