c. passive transport is for bigger molecules
d. a protein channel is used to allow passage of solutes
What is it is active transport
Why is equilibrium not the goal of metabolic pathway?
What is products need to be continually made and broken down.
If a reaction has a positive free energy is also....
a. Is non spontaneous
b. Is exergonic

c. Recovery or reformation of the carbon acceptors
d. none of the above
What is pulling carbon from atmosphere
What is the difference between passive transport and active transport?
What is....
Active uses energy (ATP), Molecules move low to high
Passive doesn't use energy (ATP), Molecules move high to low
What reaction has spontaneous and releases energy
Exergonic or Endergonic
What is exergonic
How can a reaction overcome activation energy?
What is Heat and Enzyme
What does photosystem 1 help with....
What is reducing NADPH+ to NADPH
Which transport has different concentrations than their environment
Active or Passive
What is active transport
Is equilibrium work better with diffusion or metabolism and why?
What is diffusion because the particles are still moving.
Metabolism mean everything has stopped
