What is ATP?

(Adenosine triphosphate)
This type of molecule contains a sugar group, a base and THREE phosphate groups. (Hint: When the 3rd phosphate group bond is broken, this a lot of energy is released)
400

What is a hypotonic solution?
What is a hypertonic solution?
A) Solution has more particles inside the cell than outside and may cause a burst
B) Solution has less particles inside the cell than the outside and may cause dehydration and shrinkage

What is a monosaccharide?
Carbohydrates are broken down into basic smaller units called _______________________. (Hint: the opposite of polysaccharides)
500
What are simple (sugar) and complex (starch) carbohydrates? Sugars are tested with Benedict's Solution which must be heated, and starch with iodine solution.
What are the two types of carbohydrates? How can we test for each? Provide two examples of each carbohydrate.

Selective permeability is the process in which the membrane allows only certain materials to enter and exit the cell. This helps maintain homeostasis because unwanted materials that may cause damage to the cell, may not enter.
Define selective permeability and explain how it is important for maintaining homeostasis.
