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 fun
What best describes the cytoskelton?
The fluid contained within the cell membrane containing all the organelles, enzymes and substances required for cellular fun
A network of protein filaments that extends throughout the cytosol
Tubular membrane structure continuous with rER
What are the key fun
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
Which of the below are part of the endomembrane?
Smooth endoplasmic reticulum
Mitochondria
Lysosomes
Vesicles and vacuoles
Golgi apparatus
Rough endoplasmic reticulum
Nucleolus
Cytoplasm
Pick all that apply for the endomembrane system fun
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 fun
Main site of protein synthesis within a cell
Muscles = storage of Ca++ which is released during contraction
Which applies to rough endoplasmic reticulum?
Specialist fun
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
