Answer:
The way they sound. like the way they type if that makes sense
The two cells of the similar shape, and size have different levels of the ongoing metabolic activity. On one hand, the cell a is metabolically quiet, which means that no energy consuming chemical reactions are taking place in this cell. On the other hand, the cell b is actively consuming the surrounding oxygen. In this scenario, the oxygen will more quickly diffuse into the cell b because the diffusion gradient for oxygen in this cell is steeper than in the cell a.
Hence, the blanks can be filled with 'b and the diffusion gradient is steeper' respectively.
Normally when one studies an enzymatic reaction you need to do the following:
1. The initial rate of the reaction - or initial velocity - Vo - (when you've just combined the enzyme and the substrate) - you measure the amount of product made per unit time right at the beginning of the reaction.
2. You have to do this for each concentration of substrate - this would be a range of substrate concentrations.
3. You plot these on a graph with (substrate, Vo) as your (x,y)
What you will see is a graph that rises from 0,0 and eventually plateaus.
The plateau indicates that the enzyme is saturated with the substrate and is working as fast as it can. This is the maximum velocity or Vmax.
Probably temperate deciduous because it experiences fall and winter (hope this helps and feel free to correct me if I'm wrong)
