Chapter 5 - Cell Structure



Functional Anatomy of Cells

For this section, you should be able to indicate:




The Typical Cell

For this section, you should be able to indicate:




Cell Structures

For this section, you should be able to indicate:




Cell Membranes

The cell contains a variety of cell membranes. The outer boundary of the cell is the plasma membrane.

Cells also contain membranous organelles. We’ll look at organelles shortly.




Membrane Structure

For this section, you should be able to:

Here are my notes about Membrane Structure




Membrane Function

For this section, you should be able to:

Here are my notes about Membrane Function




Cytoplasm and Organelles

For this section, you should be able to indicate:

The area outside of the nucleus of a cell is known as the cytoplasm. The cytoplasm contains two parts: the cytosol and the organelles. The cytosol is the liquid portion of the cytoplasm.

In the upcoming sections, we’ll look at various organelles and we’ll learn which ones are membranous and which ones are non-membranous.

A good root word to know is cyto-. It means “cell.” Actually cyt is the root word and “o” is what we call the connecting vowel. This root word will show up quite a few times in anatomy so learning what the cyt means will be invaluable.

In this section, you’ll be learning about the following:




Endoplasmic Reticulum

For this section, you should be able to:

Here are my notes about the endoplasmic reticulum




Ribosomes

For this section, you should be able to indicate:

the location of ribosomes in the cell
the structure, chemical makeup and the function of ribosomes
* the name of the structure that consists of many ribosomes attach to a messenger RNA molecule

Here are my notes about ribosome




Golgi Apparatus

For this section, you should be able to:

Here are my notes about the Golgi Apparatus




Lysosomes

For this section, you should be able to indicate:

Here are my notes about lysosomes




Proteasomes

For this section, you should be able to indicate:

Here are my notes about proteasomes




Peroxisomes

For this section, you should be able to indicate:

Here are my notes about peroxisomes


Mitochondria

For this section, you should be able to indicate:

Here are my notes about mitochondria




Nucleus

For this section, you should be able to indicate:

Here are my notes about the nucleus



Cytoskeleton

The cytoskeleton is the supporting framework inside of the cell.

In this section, we’ll look at:




Cell Fibers

For this section, you should be able to:

Here are my notes about the cell fibers




Centrosomes

For this section, you should be able to indicate:




Molecular Motors

Just read this section. There are no objectives.




Cell Extensions

In this section, you’ll learn about:




Microvilli

For this section, you should be able to indicate:

MIcrovilli are found on the surface of cells on the surface of the small intestine. These cell extensions increase the surface area that is available for the absorption of food molecules.




Cilia

For this section, you should be able to indicate:

Here are my notes about the cilia




Flagella

For this section, you should be able to indicate:

Here are my notes about the flagella




Cell Connections

For this section, you should be able to indicate that the direct cell connections are:




Desmosomes

For this section, you should be able to indicate:




Gap Junctions

For this section, you should be able to indicate:




Tight Junctions

For this section, you should be able to indicate:

Here are my notes about the tight junctions





Chapter 6 - Cell Function

In this chapter, there are two main topics: Membrane Transport and Cell Metabolism.



Membrane Transport

In this section, you’ll look at:




Overview of Membrane Transport

For this section, you should be able to indicate:

Here are my notes about the overview of membrane transport. On this page, you will can watch a video that explains the difference between passive and active transport.




Passive Transport Processes

For this section, you should be able to:

They three types of passive transport are:
* Diffusion
* Simple Diffusion
* Osmosis




Diffusion

For this section, you should be able to:

Here is a video about diffusion




Simple Diffusion

For this section, you should be able to indicate:

Here are my notes about simple diffusion




Osmosis

For this section, you should be able to:





Facilitated Diffusion

For this section, you should be able to:




Filtration

For this section, you should be able to indicate:

For this topic, read Box 6–3 Filtration




Active Transport Processes

For this section, you should be able to indicate:



Transport by Pumps

For this section, you should be able to:




Transport by Vesicles

or this section, you should be able to:

Here are my notes about transport by vesicles




Cell Metabolism

Metabolism

For this section, just remember what was learned earlier about metabolism, catabolism, and anabolism.

Metabolism refers to the chemical reactions that occur in the body. There are two aspects of this: catabolism and anabolism.

Also, in the body, chemical reactions are typically found as a series of chemical reactions called a metabolic pathway.

A –> B –> C –> D, etc.

Catabolic pathways
In catabolic pathways, chemicals are broken down and when the chemical bonds are broken, energy is released.

Anabolic pathways
In anabolic pathways, larger, complex molecules are made by forming bonds between smaller molecules, which requires an input of energy.
