Describe how enzymes break down food.

1 answer:

6 0

They work like a catalyst. Enzymes help to speed up the rate of chemical reaction in the digestive system. They do this by decreasing the amount of activation energy required to start the reaction. Protease break down the protein, Amylase help to break down the carbohydrates and lipase break down fats into smaller components as food would be too big for us to swallow.

Two solutions will be prepared with the mixture of distilled water and stock solution of KMnO4 (10 mM). Give the correct volumes

Yanka [14]

Answer:

See the answer below

Explanation:

<em>Recall that the law of dilution states that the number of moles before dilution must be equal to the number of moles after dilution.</em>

Mathematically,

molarity x number of moles before dilution = molarity x number of moles after dilution.

For solution A: final molarity = 3 mM, final volume = 2mL, initial molarity of KMnO4 = 10 mM

Applying the equation:

10 x initial volume = 3 x 2

initial volume = 6/10 = 0.6

<u>Hence, Tube A should be made with 0.6 mL of 10 mM KMnO4 stock and 1.4 mL of distilled water to give a solution of 2 mL 3 mM KMnO4.</u>

For solution B:final molarity = 8 mM, final volume = 2 mL, initial molarity = 10 mM

10 x initial volume = 8 x 2

initial volume = 16/10 = 1.6

<u>Hence, Tube B should be made with 1.6 mL of 10 mM KMnO4 stock and 0.4 mL of distilled water to give a solution of 2 mL 8mM KMnO4. </u>

Osmosis is the diffusion of water across a membrane in response to the concentration of one or more of the ________.

kondaur [170]

Osmosis is the diffusion of water across a membrane in response to the concentration of one or more of the <u>higher concentration</u>

Osmosis is the movement of water molecules from a region of lower concentration to a region of higher concentration through a selectively permeable membrane

It is a special case of diffusion of water across a membrane in response to the concentration of one or more of the higher concentration

<h3>What is diffusion?</h3>

Diffusion can be defined as the movement of substances from a region of higher concentration to a region of lower concentration
