CORRECT ANSWERS (100% CORRECT VERIFIED SOLUTION)
NEWEST UPDATED VERSION |GUARANTEED PASS.LATEST
UPDATE FOR 2026-2027
What is the society of cells
Simplest structural unit of complex
organism Some have to be specific
Ie muscle cells: contraction
Kidney cells: filters blood
Nerve cell:signals
Differentiation
process in which stem cells become specialized in structure and
function
what is the internal enviroment?
what the cell sees, relatively constant but changes with stressors
,negative feedback loop
Causes a system to change in the opposite direction from which it is
moving The response counteracts the stimulus,shutting off the
response loop
Ie, high substrate [] ->needs to decrease-> brings back to homeostasis-
> realizes and stops once enough has been broken down
positive feedback loop
Causes a system to change further in the same
direction. Can proposer a signal to help decrease
energy being used Quick response
Outside factor required to shut off feedback
cycle Ie. child birth
what is cellular physiology?
how cells communicate with internal and external enviroments and
how this is regulated
does the hydrophillic (head) or hydrophobic (tail) side of a
phospholipid face outwards?
hydrophillic
,what else can be embedded in a phospholipid bilayer?
proteins
whats the purpose of a phospholipid bilayer?
surround something e.g. water (very fluid, like oil on water)
what type of membrane is used in the fluid mosaic model?
semi-permeable membrane- allow for containment (cellular contents),
allow energy gradients, allow signal transduction
What is membrane fluidity and what determines this
Phospholipids make up membrane and composition which is very
important
Why is the composition of selected membranes different
, Ribosomes
Small dense granules of RNA and protein that are essential for
protein synthesis from DNA
Poteasomes
Protein cylinders with a protein to peptides which is a safe net
mistakes
Ie when we make a mistake, it can't do it's normal function this cell
brings it here and proteasomes break them down
Centroles
Composed of microtubules and are associated with nuclear
division. Found in the centrosome.
Direct DNA during cell
division Part of
cytoskeleton
Centrosomes
Microtubule-organizing centers that help to form and organize the
mitotic spindle during mitosis
Cristae of mitochondria
increase surface area which allows us to hold more protein =more
energy
