You set up 5 samples that contained a range of sucrase concentrations but the same amount of
substrate (sucrose)
- the ph was kept constant in all tubes by using the same amount of buffer
- the temperature was kept constant in all tubes (room temp)
- a negative control was used (without the substrate sucrose) to prove that this reaction is due to enzyme activity. it is important
to establish this, because sucrose can break down on its own to yield glucose and fructose but this reaction would take much
longer without enzyme
- there was no quantitative data, but a color key was used to distinguish between maximum, medium and low enzyme activity
- by graphing the qualitative data, you observed that the reaction increases as the enzyme concentration is increased. this
means, the more enzyme, the more sucrose can be broken down, the more products can be formed.
- however this effect can be observed up to a limit.
as stated, the results as evidenced in the experiment can only be observed up to a limit. why?
a buildup of sugars alters the ph of the environment
the products, glucose and fructose, denature the sucrase
you eventually run out of sucrose to act as the substrate
the reaction causes a change in temperature, that denatures the sucrase.
eliminate

You eventually run out of sucrose to act as the substrate.

Explanation:

You must have both substrate and an enzyme for the reaction to continue.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !
