The model attached represents facilitated transport, which is answer choice D. In the model, there are protein channels, which allow molecules to pass through them if they're too large to fit through the aquaporins (making diffusion an incorrect answer.) We can eliminate active transport since ATP isn't used to control transport, and we can eliminate endocytosis as it is a form of active transport. The remaining answer would be facilitated transport, which is a form of passive transport. Hope this helps! :)
D. Electrons because isotopes deal with electrons.
The lock an key analogy is used because each enzyme has specific substrates that fit into it. This is like how locks only work with a specific key. The enzyme is the lock and the substrates are the key.

This analogy is not perfect because there are often multiple substrates for each enzyme reaction. It only takes one key to turn the lock. The reaction is also taking place between the substrates themselves and not the enzyme. In the lock and key analogy, the lock is affected by the key, but in an enzyme reaction, the substrates are affected by the enzyme.
Hope I’ve helped ;)
Answer:
The rate of activity of an enzyme might change as pH changes
Explanation:
Enzymes are organic catalysts that controls the rate of a specific chemical reaction.
These materials combines substrates in order to lower the activation energy which might serves as a barrier to chemical action.
- Enzymes have specific reactions which they control.
- Temperature and PH conditions control the rate at which enzymes work.
- They are not all produced from the building block of carbohydrates.
Answer:
El agua es un medio ideal para reacciones químicas, ya que puede almacenar una gran cantidad de calor, es eléctricamente neutral y tiene un pH de 7.0, lo que significa es que no es ácida ni básica. Además, el agua participa en muchas reacciones enzimáticas como agente para romper enlaces o, al eliminar de una molécula, para formar enlaces.
