Type of junction that allows many things through rapidly. An example is the heart.
What is a gap junction?

A sodium potassium pump pumps Na and K ions in opposite directions across the membrane from low to high concentrations. What kind of transportation and transport are used?
Active transport and antiport

What does exergonic mean, and what kind of delta G is associated with it?
Exergonic means to release energy. A negative delta G is associated with this. A negative delta G means you have energy.

38 ATP
What is the total amount of ATP produced in all three cycles of cellular respiration?
300
Oxygen (Hint: involves one of the cycles of cellular respiration)
What is the final hydrogen catcher in the ETC?
400
Mitochondria and Chloroplast
What are the two organelles that make energy?
400
Name and define the four different types of transportation. (Hint: has to do with diffusion)
Passive diffusion- high concentration to low with no help
Facilitated diffusion- high to low; help from protein
Active transport- low-high; help from ATP
Osmosis- the passive diffusion of water

The reaction of A+B->C has delta G +7.2 kcal of energy. An enzyme was activated in order to speed up the reaction and lower the activation energy. Will the delta G from the reaction increase or decrease?
Neither! There is a specific delta G for every reaction and it will NEVER change!

When NADH and FADH are oxidized in the ETC, what kind of transportation/transport occurs?
Active transport/uniport
400
Name at least two poisons and what they do
DNP - blows holes in the christae membrane
Rotenone - blocks protein channel one so hydrogen can't get through
Oligomycin - Blocks the ATP synthase
Cyanide/Carbon Monoxide - Blocks area where oxygen is supposed to pick up hydrogen

UPS of the cell that receives products from the ER. UPS of the cell
What is the golgi apparatus?

A cell has 80% solvent. The beaker that the cell is in contains 10% solute. What is the cell in relation to the solution? What will happen to the cell?
The cell is hypertonic in relation to the solution. The cell will swell, burst, or lyse.

Delta G = +4.2 kcal of energy
Which reaction can be coupled to it?
Delta G = +5.6 kcal
Delta G = -5.6 kcal
Delta G = -3.2 kcal
-5.6 kcal

What is made in the kreb's cycle if you have 2 glucose? How many turns of the cycle is this?
2 glucose = 4 turns of the cycle
12 NADH
4 FADH
4 ATP

What happens when something is oxidized? What happens when something is reduced? Which is an endergonic process and which is exergonic?
Oxidize - to lose electrons (exergonic)
Reduce- to gain electrons (endergonic)
