(2nd Qtr) Cell Transport Mechanism

What structure of the cell could have malfunctioned if there is an unregulated movement of substances in and out of the cell?

• Plasmodesmata

• Cell Membrane

• Centriole

• Centrosome

It is tucked between the hydrophobic tails of the phospholipids.

• Integral Proteins

• Cholesterol

• Peripheral Proteins

• Carbohydrates

It is embedded in the phospholipid bilayer. It may or may not extend through both layers.

• Integral Proteins

• Cholesterol

• Peripheral Proteins

• Carbohydrates

It is on the inner or outer surface of the phospholipid bilayer, but not embedded in its hydrophobic core

• Integral Proteins

• Cholesterol

• Peripheral Proteins

• Carbohydrates

It is attached to proteins or lipids on the extracellular side of the membrane.

• Integral Proteins

• Cholesterol

• Peripheral Proteins

• Carbohydrates

It involves the formation of glycoproteins and glycolipids.

• Integral Proteins

• Cholesterol

• Peripheral Proteins

• Carbohydrates

The phospholipid bilayer is amphipathic (includes both hydrophilic and hydrophobic parts). Which part of the phospholipid bilayer is hydrophilic? (contains negatively charged phosphate group)

• Head

• Tail

• Body

• Radar

The phospholipid bilayer is amphipathic (includes both hydrophilic and hydrophobic parts). Which part of the phospholipid bilayer is hydrophobic? (has nonpolar fatty composition)

• Head

• Tail

• Body

• Radar

It describes the structure of the plasma membrane as a compilation of components.

• Fluid Mosaic Model

• Compiled Acidic Base Model

• Mirage Composition Model

• Lipid-Triphosphate Model

Cell surface molecules that allow cells to identify other molecules.

• Marker Molecules

• Attachment Molecules

• Filtering Molecules

• Identifying Molecules
