Chapter Three Review #2 Q’s KEY
1. Golgi Body looks like stacks of three to
twenty slightly curved sacs. See picture.
2. The main function of the GOLGI APPARATUS is
to receive in-coming proteins and lipids, then
modify them, sort them and re-package them
into vesicles and ship them off. "Shipping and
receiving warehouse"
3. A vesicle is a very small membranous
transport sac. A vacuole is also membranous
sac but it is much larger and more often used
for storage.
4. Definitely Plant – As it possesses – Cell Wall,
Chloroplast and a Large Central Vacuole.
5. Vesicles form when membrane pinches off to
form a sac. This can happen at E.R, Golgi, and
pinching in at the Cell Membrane.
6. Lysosomes are produced when hydrolytic
enzymes are packaged up and blebbed off of
the Golgi Apparatus.
7. Lysosomes store and release HYDROLYTIC
ENZYMES. – They run hydrolysis on
macromolecules to break them into their
monomers.
Lysosomes are often involved with the
digestion of : Bacteria, In-coming
Macromolecules and also the cell itself during
Apoptosis – Programmed cell death or
organelle breakdown.
8. Ribosomes are manufactured back in the
NUCLEOLUS.
9. MITOCHONDRION – Mitochondria (plural)
10. CELLULAR RESPIRATION takes place in
Mitochondria. So ATP is generated during
cellular respiration. ATP provides energy for all
cell processes.
11.
C6H12O6 + 6O2  6CO2 + 6H2O + Energy Release
Glucose + Oxygen  Carbon Dioxide + Water + ENERGY
12. These folds are necessary for increasing
Surface Area. This extra surface area is
required to house all of the enzymes that are
required to run cellular respiration.
13.
These shelf-like folds are called CRISTAE
14.
Matrix
15. Cytoskeleton is a vast network of filaments
and tubules. This cytoskeleton is responsible
for:
- Maintaining Cell Shape
- Allow for organelle movement
- Anchor things in place
Allow for motile structures and key process like
cell division.
16.
The key building structures for building the
cytoskeleton are :
A microfilament (Actin) consists of two filamentous
proteins twisted around each other in a helical manner.
Microtubules form when filamentous proteins
called TUBULIN spiral up to form a cylinder.
17.
TUBULIN
18.
9 + 0 Arrangement
9 + 2 Arrangement
19. Sperm cell – Base of Flagellum will be site
of BASAL BODY (9 + 0) while shaft of Flagellum
will be (9 + 2) arrangement.
20. The function of the basal body (9 + 0) is for
anchorage and these basal bodies direct the
organization of microtubules into the shaft ( 9
+ 2) in cilium and flagella
21. Motor- operated side arms are found
between microtubules.
22. Flagella are used for cellular locomotion.
In humans the male gamete (Sperm) need to
be motile.
23. Lysosomal enzymes would digest a neutral
fat down into a glycerol molecule and three
fatty acids if it was a triglyceride.
