What is the role of the colorful balls in the analogy?
They represent the substrates
How does the presence of a competitive friend affect the enzyme's ability to push the balls?
It reduces the number of balls available for the enzyme to push
What is the effect of the blocks on the enzyme's ability to push the balls?
The blocks make it harder for the enzyme to move, even with many balls
What is the key difference between a competitive and a non-competitive friend in the analogy?
Their effect on the enzyme's ability to push the balls
In the context of the analogy, what does the toy car represent?
The enzyme
What happens to the enzyme's activity when a non-competitive friend is present, even with an abundance of substrates?
It decreases
What is the primary difference between competitive and non-competitive inhibitors?
The effect on the enzyme's function
What is the characteristic of secondary active transport that distinguishes it from active transport?
Coupled movement of two molecules or ions
What is the driving force behind passive diffusion?
Concentration gradient
What is the source of energy for secondary active transport?
Electrochemical gradient established by primary active transport
What is the direction of movement in symport secondary active transport?
Both molecules move in the same direction
What is the characteristic of active transport that distinguishes it from passive diffusion?
Movement against the concentration gradient
