ch1 cells Flashcards
cellz (38 cards)
B___ D___ S___ (RBC adaptation, and what it is for)
Biconcave Disc Shape
1. SA:Vol increase
2. Rate, diffusion, oxygen, increase
RBC adapation?
- Has Haemoglobin
- Biconcave Disc Shape
- No Nucleus
Imagine a cell goes “Nah I want my oxygen dont take it1!!!! <: thats what happens when its irreversible”
H______ (RBC adaptation, and what it is for)
Has Haemoglobin
1. Binds, oxygen, reversibly
2. transport, oxygen, from lung, rest of body
N___N____ (RBC adaptation, and what it is for)
No Nucleus
1. Increase Space
2. Increase Haemoglobin
3. Increase Oxygen carried -> RBC
Cell wall is…? (In cell drawing)
Cell membrane is…? (In cell drawing)
Cell wall: A thick wall
Cell membrane: A singular membrane
cells are…?
- basic unit of life
- consists, many organelles, perform specific functions
- functions performed needed sustain life
material
nUcleUs structure
consider the shape and what is inside the nucleus
- spherical
- double membrane-bound
- contains genetic material
nucleus funct
- controls, all, biochemical reactions, in the cell
cytoplasm struct
- gel-like substance,
- enclosed, within, cell surface Membrane
cytoplasm funct
site of biochemical reactions
cell surface membrane struct
partially permeable membrane
made out of lipids
cell surface membrane funct
controls movement of substances,
in, out of cell
Some
Erratic
Rats
struct
- network, tubular, membrane-bound structures
- continuous -> nuclear envelope
- no ribosomes
some erratic rats scurry along the network of enclosed tubes
SER funct
synthesizes lipids
detoxification, of, harmful substances, into, harmless, materials
What is detoxification?
conversion, harmful substances -> less harmful substances
RER struct
structures
network flattened membrane-enclosed struct
continuous with nuclear envelope,
ribosomes, attached -> surface
- network flattened/tubular membrane-enclosed (struct)
- continuous w/ nuclear envelope,
- ribosomes attached on surface?
RER funct
Modifies, transports proteins -> Golgi Body
**p.s. the proteins that RER modifies are those that are synthesized by the ribosomes
protein synthesis
- Ribosomes synthesize polypeptides
- polypeptides enter RER
- where they Fold, form proteins, transported -> Golgi Body
- Golgi Body chemically modifies proteins -> functional enzymes, sorts, packages enzymes into secretory vesicles
- SV migrate -> cell surface membrane, fuses with CSM -> secrete, enzymes out of cell
dont write any shortform in exam.
Ribosome struct
small organelle, made out of, protein, RNA
Ribosome funct
Hint: in 2 areas
attached RER, cytoplasm: synthesize polypeptides
- in RER: for secretion
- in cytoplasm: be used within cell
G0lgi Body struct
- Curved stacks flattened membrane-bound structures
Its a stack of Gou Zi Ji! Its so curvy for some reason, and flat…, and its bound by an outer membrane of redness! eating it will burst that outer membrane it is bound by
G0lgi apparatus funct
and of course, recall your protein synthesis stuff
- Chemically modifies, sorts, packs, proteins, vescicles, for secretion, out of cell
this time it aint to functional enzymes dat not the main pt
based on qn context.
if qn abt. synthesis of hormones then specify.
If not, proteins.
Mit0ch0ndria struct
- Ovoid (oh no)
- double membrane-bound
- highly folded inner membrane
ah. Mitochondria is so 0void. You can almost see it. Its Mit0ch0ndria, double-membrane bound.
Its inner membrane is highly folded
Mit0ch0ndria funct
aerobic respiration, oxidises glucose, release energy, biochemical reactions
