What would be the tempeture of a pot of water if you continued heated it for 10 minutes after it had already started boiling?

What is the chemical reaction used to study enzyme activity in the lab (lactase breaking down lactose into its monomers). Know t
Bas_tet [7]

Answer: The chemical reaction in this example is Called hydrolysis in the presence of Lactase

Here is a word equation for the hydrolysis of lactose:

lactose + water → galactose + glucose

Explanation: The equation is called <hydro> + <lysis) of these terms refer to water and splitting respectively. So hydrolysis means splitting with water. Enzymes pull out a monomer by examining where the monomers are connected, and placing a water molecule in between them, resulting in the breakage of the bond between the monomers. Here are two picture to represent it.

An internal membrane system where lipid components of the cell membrane are assembled, along with proteins and other materials
MakcuM [25]
A. Lipid bilayer: the phospholipid bilayer is the membrane of a cell. The bilayer contains lipids, membrane proteins, cholesterol, receptors for various molecules, pumps to transport ions and solutes against the concentration gradient, and many other items necessary for a cell to function and work together with other cells.

b. Osmotic pressure: Osmosis is the flow of water across a semipermeable barrier from an area of low solute concentration to high solute concentration. Osmotic pressure is the lowest possible pressure to prevent this water movement.

c. Endoplasmic Reticulum: the Rough ER synthesizes proteins for use outside the cell. The Smooth ER produces lipids and some steroidal hormones.

A. Lipid Bilayer is therefore the correct answer. Osmotic pressure does not involve the various components of the cell membrane, and the ER's produce proteins and hormones. Therefore A is right.

Hope this helps! :) Let me know if you need a clarification.
