Unit 3 Flashcards
What is the equation of thermodynamics?
Delta G = Delta H - (T * Delta S)
What is entropy?
It is a constant of disorder
What G stand for
Free energy
What S stand for
entropy = disorder
Enthalpy is what
H and potential energy
What is a sponmtaneous reaction?
A spontaneous reaction is a reaction that will happen spontaneously without the help of nothing
How can ATP can help a reaction to be spontaneous?
The ATP is a source of energy and this energy will help a reaction to achieve their activation energy factor. It is like a point of non-retour that they can’t go back.
How can enzyme help with nmetabolic reaction?
An enzyme lower the actiovation energy needed for the reaction to happen so the reaction will happen faster with the need of less energy therefore accelerating some metabolical reaction.
How can an enzyme work(3)?
- Enzyme bring the molecules together
- Charge interactions
- Changing the shape of the substrate molecule.
Discuss enzyme reaction rate with the PH and temperature
Each enzyme has its own enzyme effectivity at different ph same for temp, but for temp at certaintemp an enzyme can denature and its functions is bad after.
Enzyme activity concentration
if the concentration of the enzyme is growing then the rate will increase. However if it is the substrate it will increase bu at a certain point is stop and it saturates.
What is the main difference between the areobic pathway and the anaerobic pathway?
The anaerobic pathway uses different electron transporter than O2 and it is less great since o2 is simply highly electronegative and have a greater affinity with electron therefore bein better.
Identify where the fermentation occurs if the cellualr respiration is blocked and explain why?
So the fermentation is like the back-up generatore of the cell. When oxygen is plentiful the pyruvate will enter the cell and continue its way to the krebs cycle but if not it will goes under the fermentation.
What are the two types of fermentation
alchol and lactate
Can you explain what happen to pyruvate in the alcohol fermentation?
Pyruvate is reduced to ethyl alcohol as NADH is oxydized to NAD+
Can you explain what happen to the pyruvate under the lactate fermentation?
Pyrtuvate is transformed into a three carbon molecule lactate. But in contrary to the alcohol when getting transformed to lactate if oxygen is back it will become pyruvate and act normal as the pyruvate normally.
What is the main difference between the energy requiring phase and the energy consuming phase of the glycolysis?
The atp is transformed to adp +p and in the second is that adp + p is transformed to atp
How many atps aerobic respiration do
36 to 38
How many atps anaerobic respiration do
2 to 36
