allows for appropriate reactions to take place as it keeps the conditions right for
each reaction.

The cell surface contains phospholipids and proteins. The lipids give the cell its
flexibility and firmness also maintaining its shape. The lipid layer presence can
vary between 2080% with the rest being…

2. Secondly we
encounter the
Mitochondria
which are the
cell's lungs. The
term simply means
"thread granule"
when translated
from French. They
are the energy
providers inside
the cell. The
energy is released
when the
mitochondria
respire using oxygen. This chemical adenosine triphosphate (ATP) transports
the energy which…

arranged in a 9 + 3 pattern as a ring of nine microtubules arranges in "triplets" at
90°angle to each other.

During mitosis each centriole moves to the opposite end of the cell. Then, they
being to pull apart the cell arranging the chromosomes using a spindle of…

4. Also, on our journey around the cell we are bound to find the nucleus. The
nucleus is responsible for controlling the cell and the events within it. It
functions like an administration centre. It's used to control the energy intake,
movement and reproduction within the cell. The…

and proteins can be found in the nucleolus as well. The nucleolus's main function is to
make ribosomes which are a crucial organelle during protein synthesis.

The nucleolus has a similar shape to the nucleus and can sometimes in large cells take
up to 25% of the nucleus…
