1. Enzyme interacts with substrate
.
2. Enzyme may undergo a conformational change to capture the substrate ("induced fit" model)
3. Enzyme-substrate complex may undergo several changes to form the product(s).
4. The product(s) are released
.
5. The enzyme returns to its original form. It is then ready to do the cycle all over again.
A testable hypothesis must be just that--testable. You must be able to provide evidence that your hypothesis can be proven true in order for it to be considered accurate enough for future use among scientists. This can be done through repeated experimentation.
The answer should be A. Active transport
B. Salmon envolved before kangaroos
I would think it would be C
