Cells

Question 1

what is hydrophilic?

Answer 1

hydrophilic is attracted to water.

Question 2

what is hydrophobic?

Answer 2

hydrophobic resists water.

Question 3

what is the cell membrane model referred to?

Answer 3

the fluid mosaic

Question 4

how do you know if the cell is isotonic solution?

Answer 4

there will be no flow of water in or out of the cell and the cells volume will remain stable.

Question 5

which part of the cell membrane is hydrophilic and which part of the cell membrane is hydrophobic

Answer 5

the outside of the cell membrane is hydrophilic and the inside proteins are hydrophobic.a portions of an integral membrane inside(protein) are hydrophobic. those parts that are exposed to the cytoplasm or outside fluid tend to be hydrophilic

Question 6

Question 7

How do you know if the cell is in a Hypertonic solution?

Answer 7

There will be a net flow of water out of the cells and the cell will lose its volume.

Question 8

How do you know if the cells volume is hypotonic solution?

Answer 8

There will be a net flow of water into the cell and the cell will gain volume?

Question 9

What is thefunction ofa Phospholipid?

Answer 9

It acts as a barrier to the passage of molecules and Ions into and out of the cell.

Question 10

what is the function of a polerhead?

Answer 10

polar heads contact the fluids inside and outside of the cell. because of its chemical old and acts as a semi-permable membrane.

Question 11

what is the function of a nonpolar tail?

Answer 11

to make the membrane semi-permeable.

Question 12

What is the purpose of a carbo hydrate chain?

Answer 12

The function is to recognize harmful cells.

Question 13

What is the function of the Glycoprotein?

Answer 13

Glycoproteins are molecules that comprise of protein and Carbohydrate chain that are involved in many physiological functions including immunity.

Question 14

What is the purpose of external membrane surface

Answer 14

Is to keep all the unwanted substances out of the cell and is also used to be a gate allowing transport into the cell of essential nutrients.

Question 15

What is the purpose of a Phospholipid layer?

Answer 15

Phospholipid bilayers create a selectively permeable barrier to the movement of ions and molecules important for celluar function.

Question 16

What is the purpose of the Cholesterol?

Answer 16

fat like waxy substances that makes your body make cell membranes,many hormones, and Vitamin D.

Question 17

What is the purpose of the transport protein?

Answer 17

cell membrane transport protein by categorizing the translocation of solutes, including Ions ,nutrients, and neurotransmitters across biological membranes.

Question 18

What is the purpose of cytoskeleton filaments?

Answer 18

The cytoskeleton is a structure that helps cells maintain its shape and internal organizations.
