In what organelle does cellular respiration take place?

mighty mitochondria

Name two storage organelles?

Vesicles, ER-

What is the list of organelles that take part in protein synthesis?

Nucleus (transcription), ribosomes (translation)-free and fixed (Rough ER)

How is the nucleus involved in protein synthesis?

transcription

What do ribosomes di? Are they found freely floating in the cytoplasm? OR are they found attached to another organelle? OR both. Explain why this occurs.

Protein synthesis. both; depends on the destination of the protein (to stay inside the cell=free; cell membrane or leave the cell=fixed)

What does the endoplasmic reticulum do?

Rough - make proteins; Smooth-makes lipids, detox. Sends material to golgi to be shipped

What is the difference between rough ER and smooth ER? What is the ER doing that is different in each case?

See above

What are lysomsomes?

"cleaners"

What type of molecules would be found inside the lysosome?

Special enzymes (protein) to degrade materials.

In what organelle do molecules move from the ER to the Golgi bodies

vesicle

What is meant by "membrane turnover"?

Components of the membranes are always, always, always being replaced, recycled, reused.

What is a centriole?

used for mitosis

What is the difference between chromosomes and chromatin?

chromosomes - (condensed: preparing for mitosis)
chromatin - (not condensed)

What do they each have to do with DNA?

they are DNA and histones

What is flagella?

for motion

How does flagella differ in size and number from cilia

there are not very many flagella compared to cilia

Which organelle can convert sugar (glucose) and oxygen into ATP (energy molecule), carbon dioxide and water?

mitochondria

What is the process in number 17 called

cellular respiration

What is the molecular composition of the cell membrane?

phospholipid bilayer, proteins, carbohydrates

What is the cytoskeleton made up of?

proteins - filaments

What organelles are responsible for transport of some kind?

vesicles

What is the molecular composition of the cell membrane? Howw are these molecules arranged in the membrane?

phospholipid bilayer, proteins, carbohydrates

What is the value of cell membrane structure of having both polar and non-polar phospholipids ends?

selective permeability

What are the different types of functions proteins present in a cell membrane can have?

MANY - carrier, adhesion, channel (see powerpoint)

Which part of the cell membrane actually CONTROLS which molecules can enter and leave a cell?

carrier proteins

Do you think that the membranes around each organelle contain different types of proteins with different types olf properties? Why or why not?

yes, based on the molecules that come and go from the organelle.

What is the difference between a cell that is prokazryotic and a cell this is eukaryotic?

nucleusWhat are teh two types of nucleic acid molecules found in cells? what is the role/function of each? RNA, DNA (see powerpoints)
