Organelles
Rough endoplasmic reticulum is different from smooth endoplasmic reticulum because it is covered in
ribosomes
Basic unit of life
cell
What phase does the cell spend most of its time in?
interphase
This type of movement goes against the concentration gradient (passive or active)
active
The more common feedback system
negative feedback loop
Organelle that packages and exports proteins. Some call is the "packaging plant"
Golgi Apparatus/complex, etc
To find the number of __________, you subtract the number of protons from the atomic weight that has been rounded to the nearest whole number
neutrons
During which phase does the nucleolus disappear?
prophase
The movement of water chasing a solute is _________, which is __________ (active or passive)
osmosis, passive
Anything that disrupts homeostasis is called a(n)
stressor
3 regions of the cell
Cell membrane
cytoplasm
nucleus
What are the 4 most abundant elements in the body?
hydrogen, oxygen, carbon, and nitrogen
DNA replication occurs when? (Be specific)
S (synthesis) phase in interphase
Some molecules that are large cannot pass through the semi-permeable membrane of the cell membrane and need to travel through a channel. If no ATP is required, what type of transport is this? (be specific)
facilitated diffusion
Childbirth is an example of this feedback system
positive
This structure is technically not an organelle because it doesn't have a membrane. It is the site of protein synthesis
ribosomes
Ions serve many functions, but your lecture mentioned 3. Name 1
-carry electrical charge
-buffer blood pH
-strengthen bones and teeth
When does cytokinesis occur? Be specific
telophase (some source say the cleavage furrow begins in anaphase)
This type of endocytosis involves engulfing a fluid and requires ATP
pinocytosis
The right lobe of the liver and the right kidney are ______________ structures (what term describes the location of two structures)
ipsilateral
Where is the majority of ATP produced?
mitochondria
What is the weakest type of bond?
hydrogen
In anaphase, ___________ (chromosomes, chromatin or chromatid) are pulled to opposite poles
chromatids
Name 3 types of passive transport
diffusion, facilitated diffusion, and osmosis
This plane divides the body into anterior and posterior portions
frontal or coronal
