Chapter 7, Problem 44A

Summary Introduction

To summarize:

The relationship between the amount of glucose and rate of diffusion.

Introduction:

The movement of molecules from an area of higher concentration to lower concentration area is termed as diffusion. Diffusion is mainly seen in liquid and gaseous particles, as these particles can move easily. By this process, many molecules move in and out of living cells.

Explanation of Solution

From the given graph, it is seen that as the amount of glucose increases, the rate of diffusion also increases. This means that as glucose concentration is increases, then the rate at which these molecules move across membrane also increases simultaneously. But, after some time, the rate of diffusion becomes constant. This means, now when glucose concentration increases, there is no increase or decrease in rate of diffusion now.
