Bile,pH and Temperature, Enzyme Activity

Question 1

Pattern between temp and enzyme activity

Answer 1

As the temperature increases, the enzyme activity also increases

Question 2

What is optimum temperature

Answer 2

Temperature at which the reaction is highest

Question 3

Beyond the optimum

Answer 3

Beyond the optimum temperature, rate of reaction drops rapidly.

Question 4

pH

Answer 4

Potential of Hydrogen

Question 5

on the pH scale if is below 7

Answer 5

It is an acid

Question 6

If the PH is 8+

Answer 6

It is an alkaline

Question 7

How does the pH affect the way an enzyme works

Answer 7

The pH can affect the shape of the enzyme

Question 8

As of the shape of the enzyme changing shape….

Answer 8

It changes the shape of the active shape

Question 9

Does the pH interfere with bonds

Answer 9

Yes

Question 10

Bile

How does it work

Answer 10

Step 1

It is made in the liver

Question 11

Step 2

Answer 11

Stored in the gall bladder

Question 12

Step 3

Answer 12

Alkaline to neutralise hydraulic acid from stomach

Question 13

Step 4

Answer 13

Emulsifies fat to form small droplets

Question 14

Emulsification

Answer 14

When a large drop of oil turns into small droplets as of bile

Question 15

How does bile help

Answer 15

As of the bile turning it into small droplets it increases the surface area

Question 16

What is it broken down by

Answer 16

Lipase

Question 17

What does alkaline bile do

Answer 17

Neutralises the acid to give a high pH for the enzymes from the pancreas and small intestine to work well

Question 18

Is bile an enzyme

Answer 18

No as it does not break down fat molecules. Instead it emulsifies it
