Which of the below best describes cytoplasm?

A network of protein filaments that extends throughout the cytosol

Controls cell activity via gene expression

The fluid contained within the cell membrane containing all the organelles, enzymes and substances required for cellular function

What best describes the cytoskelton?

The fluid contained within the cell membrane containing all the organelles, enzymes and substances required for cellular function

A network of protein filaments that extends throughout the cytosol

Tubular membrane structure continuous with rER

What are the key functions of the cytoskeleton?

Provides scaffolding to determine cell shape

Site of majority of intracellular metabolism

Aids movement of chromosomes during cell division

Organisation for cellular contents

Aids movement of organelles within the cell and movement of whole cells e.g. phagocytes

Separates nucleus from cytoplasm

Which filament of the cytoskeleton is the smallest?

Acting microfilaments

Microtubules

Intermediate filaments

Which applies to centrioles of the cytoskeleton?

Short hollow cylinders composed of microtubules

Long dense cylinders composed of microtubules

Positioned at right angles to each other

Positioned opposite each other

Form part of the centrosome - the main microtubules organising centre of the cell

Involved in the organisation if the miotic spindle and completion of cytokinesis

What applies for the nuclear envelope?

Area of condensed DNA where ribosomal sub units are made

Separated the nucleus from the cytoplasm

Composed of two phospholipid bilayer

Pick all that apply for the endomembrane system functions

Protein synthesis

Lipid/phospholipid/fatty acid synthesis

Protein packaging

What applies to smooth endoplasmic reticulum?

Ribsosomes are attached

No ribosomes are attached

Tubular membrane structure continuous with rER

Specialist function in the liver- detoxification

Main site of protein synthesis within a cell

Muscles = storage of Ca++ which is released during contraction

Which applies to rough endoplasmic reticulum?

Specialist function in the liver- detoxification

Network of flattened membrane sacs that create a maze

Ribosomes attached to the outside

No ribsosomes attached

Packages into transport vehicles to be sent to golgi apparatus

What applies to the golgi apparatus?

Network of flattened membrane sacs that create a maze

Stack of flattened 'pancake like' membrane sacs in which enzymes attach to CHOs and lipids to proteins

Packages into transport vesicles

Acts as a protein packaging plant

Can package materials to be moved within and out of the cell

Vesicles exit via trans face

What applies to the mitochondria?

The powerhouse responsible for ATP

Packages into transport vehicles to be sent to golgi apparatus

Involved in cellular water control

The inner membrane is called the cristae

The inner membrane is called the crystal

What applies to ribosomes?

Ribosomes follow the instructions from the nucleus via mRNA

Can occur individually or in groups

Are the powerhouses for ATP production

Vesicles and vacuoles

Vacuoles are smaller than vesicles

Vesicles are smaller then vacuoles

Vesicles fuse with the membranes of cellular components - vacuoles do not

Vacuoles fuse with the membranes of cellular components - vesicles do not

They are membrane bound sacs required for storage and transport

What applies for lysosomes?

They are membrane bound sacs required for storage and transport

Membranous sacs of varying size containing hydrolase enzymes

Digestive factor for proteins, fats and CHOs

May combine with phagocytic vesicles to digest invading organisms

Also known as suicide sacs

Can fuse with other membranes

What applies for peroxisomes?

Similar to lysosomes

Different to lysosomes

Involved in breaking down fatty acid

Involved in breaking down proteins

Involved in detoxification

Provide an oxidative burst against invading organisms
