Introduction to the Human Cell

Question 1

What is the Endoplasmic Reticulum?

Answer 1

Complex system of flattened sacs called cisternae which is connected to BOTH the nuclear and cell surface membrane.

Question 2

What are the two different types of Endoplasmic Reticulum?

Answer 2

Smooth E.R

Rough E.R

Question 3

Describe the role of the Smooth Endoplasmic Reticulum in the cell.

Answer 3

Smooth E.R is responsible for the synthesis and transport of lipids and carbohydrates within the cell.

Question 4

Describe the role of the Rough Endoplasmic Reticulum in the cell.

Answer 4

Provides a large surface area for the synthesis of proteins, and a pathway for the transport of materials throughout the cell.

Question 5

According to the Fluid Mosaic model, what makes up the Cell surface membrane?

Answer 5

Phospholipids (phosphate head and lipid tail)
Glycolipids + Glycoproteins.
Cholesterol 
Carrier Proteins/ Channel proteins. 
Receptor Molecules

Question 6

Describe the role of Mitochondria within the Cell.

Answer 6

Mitochondria is often called the powerhouse of the cell and is the site at which aerobic respiration in the cell takes place. More mitochondria= more metabolically active cell.
