Question

What are the functions of the following?:-
1) Fluid matrix
2) Mitochondria
3) Endoplasmic reticulum
4) Golgi body
5) Lysosome
6) Ribosome

Answer 1

Easy language -- this is not homework.

Answer 2

Oh. Do you want to start, and then we can correct you?

Answer 3

I have no idea. I am not taught this stuff. I just learnt it on my own. Though, I know that one of them is called 'suicide bag'. I don't remember which one.

Answer 4

Potentially related or not related hint: "Lyso-" prefix is derived from "to lyse", which means to break.

Answer 5

Maybe we could give a hint for each one? hmm

Answer 6

Oh, so the suicide bag is lysosome, right?

Answer 7

We call it euthanasia in the States.

Answer 8

Okay, continue :)

Answer 9

This organelle has its own DNA, and also happens to work the Krebb's cycle as well as the electron transport chain through electrochemical gradients between the intermembrane space and the inner membrane.

Some say it's a symbiotic prokaryote.

Answer 10

@badreferences That's mitochondria

Answer 11

I see. Continue, please. What is fluid matrix? What kind of fluid does it contain?

Answer 12

Lol, sam - the idea we are giving descriptions for Parth to answer :)

Answer 13

I have never heard the term before. @TranceNova ? I conjecture it probably refers to the cytoplasmic fluid, for anaerobic respiration?

Answer 14

Yes - I haven't either, also just assumed it is the cytoplasm.

Answer 15

lol, I messed up

Answer 16

There's only one solution, @.Sam. . When you mess up, you must http://en.wikipedia.org/wiki/Seppuku .

Answer 17

No worries :) Though Parth given its referred to as the "matrix" what do you think this means for its function?

Answer 18

I had figured "matrix" to be a ambiguously thrown-around term. Also, don't actually seppuku.

Answer 19

I wouldn't do that, and I'm not japs :)

Answer 20

Umm. Does it contain fluids for digestion?

Answer 21

I'm unsure. A lot of metabolism happens in the cytoplasmic fluid. Digestion sounds extracellular, though; that belongs primarily in the stomach cavities.

Answer 22

According to Wikipedia, post-digestion macromolecules are present in the cytoplasm.

Answer 23

Yeah the cytoplasm does lots of things (that is it contains alot of helpful molecules) but that wasn't really what I was going for, it has one rather significant function. Think of what the "matrix" would imply.

Answer 24

I forgot the names of the processes in the digestive system :| I am so bad at Biology.
1) Intake
2) Digestion
3) Something that started with 'C' and meant the process when the energy accumulates in the blood?
4) Excretion

Answer 25

Out of luck here. I'm terrible at physiology. The only bio I did was cell/stem cell/neuro.

Answer 26

Darn, I was going to leave that to you :P I don't remember any digestion stuff either - still can look it up :P

Answer 27

still we haven't finished the cellular things yet lol.

Answer 28

Oh, the one that I asked was absorption.. and now I recall the process - assimilation.

Answer 29

It didn't start with a 'C' :P.. well continue :)

Answer 30

Alright, let's move past digestion. This organelle is primarily divided into two parts. One part is responsible for protein/membrane synthesis, while the other does everything else (lipids, steroids, etc). These represent in many ways factories.

Answer 31

Okay.

Answer 32

Does Endoplasmic Reticulum help in the transportation of the cell?

Answer 33

Transportation within the cell or movement of the cell through your bloodstream?

Answer 34

Oh! And what about the Golgi body?

Answer 35

The Golgi body is primarily for "packaging"; adding biochemical markers to bodily productions so they can move through superselective membranes more easily.

Answer 36

Microtubules, which are responsible for intracellular transportation, have motor proteins like kinesin (?) and dyenin. I assume they're constructed by the RER.

Answer 37

Yeah. Nothing is written in my book except "It helps in packaging materials"

Answer 38

Extracelullar transportation I don't think is regulated by the cell itself, lacking flagella. You could argue that the prevalence of microtubules allow contraction/expansion propulsion, but I'm not sure if this is the case.

I'm pretty sure that blood pressure/flow is all that's responsible for extracellular movement.

Answer 39

lol, my book has too much written, I'm having trouble boiling it down - looks like badref's is the go-to man for this :P none-the-less my book says "is involved in the processing and packaging of glycoprotiens and polysaccharides"

Answer 40

I see. I now understand all of it.. but wait. What are Ribosomes and Lysosomes?

Answer 41

Well we seem to have resolved Lysosomes "suicide bag" or probably a better term - the bin. Do you have anything in your mind about ribosomes?

Answer 42

Oh wait. Yes. We already did Lysosomes. And no }:(

Answer 43

While the RER is responsible for producing what I think are cellular utility proteins, the ribosome is responsible for directly converting the DNA into proteins. I think you know the process. Transcription, translation.

Answer 44

Nah. I don't really know the advanced stuff involved. I am just a kid. MERCY ON ME! >:P

Answer 45

Lol! Really Parth - you are doing really well :) Do you understand what he means by "directly converting the DNA into proteins"

Answer 46

Why would someone want to convert their DNA into proteins? DNA is the thing that carries all the genes, but why will someone convert it into proteins?

Answer 47

Well, that's wrong, actually. It doesn't directly convert. :P

mRNA is transcribed from the DNA through base pair matching (AUCG vs. ATCG, I believe). DNA itself is just a collection of sugars, nitrogen, and phosphate, so it has very little reactive potential wound up like that. Not to mention you want to keep your DNA for future reference, not have it thrown around.

mRNA then is sent to the ribosome, which says, "Okay, here are some codes from the DNA that tell you what working amino acids we need to create useful proteins that can actually react in our body."

The ribosome then tells the tRNA to go around and collect the necessary base amino acids, bring them together, and match them with the DNA->mRNA copy. This is called translation.

Answer 48

Oh no D:> That chicken scratch. Take my medal for writing it down though :>

Answer 49

Thank you @TranceNova @badreferences !

Answer 50

Ahhh it was all badrefs lol

Answer 51

lol!

Answer 52

I was the wrong one in the first place for saying "directly convert". I shouldn't type science as informally as I normally type.

Answer 53

\(\Huge \cal{\text{Thank you, Smarty-pants :D}}\)
@badreferences

Answer 54

\[\text{Thanks for not using comic sans.}\]

Answer 55

lol

Answer 56

agreed badrefs! lol
