False. Fusiform
Name the molecule that functions to stabilize the membrane.
Cholesterol
Which structure of the cell is used to determine transplant compatibility?
glycocalyx
Which molecule(s) acts as an ID tag for the cell?
glycoprotein/glycolipid
what is the change over time in the genetic composition in a population?
evolution
Which metabolic process generates the most acid?
cellular respiration
what is the range for blood pH?
7.35-7.45
Indicate the tonicity
Liver cells contain a high conc of glycogen while very little to none is found in the ECF
ICF is 0.9% solute conc. while the ECF is 9.0% solute conc.
The cytoplasm has a measured conc of 300 mOsm/L of solution. The ECF has an equivilent measured conc.
hypotonic
hypertonic
isotonic
what feedback mechanism is reversing or negating a change
negative feedback
Shake or no shake?
Tamiflu oral suspension is prescribed for a 5yr old child that cant swallow pills yet
Liquid Tylenol purchased OTC
Liquid amoxicillin prescribed for an ear infection must be mixed prior to filling prescription; it separated easily upon standing
Pedialyte: an electrolyte drink to rehydrate individual suffering from vomiting and diarrhea
Milk of magnesia for constipation is a mixture of magnesium hydroxide “milk” in water
An osteopathic doctor recommend gelatin to his patient who had a stress fracture; good source of protein
Shake: suspension
No shake - solution
Shake
No shake - solution
Shake
No shake - colloid
Give the 3 tenants of cell theory
cells are smallest unit of life, genetic material, all living things are made up of cells
what is the fluid between the nucleus and surface membrane?
cytoplasm
what is the value of positive feedback mechanism? what are 3 examples?
happens quickly, amplifying (blood clotting, childbirth, fever)
what is the supportive framework of protein filaments and tubules?
cytoskeleton
what is the clear fluid that the cytoskeleton, organlles, and inclusions are embedded in?
cytosol or ICF
Name the 3 types of gated channels.
ligand(molecule binds to protein), mechanical/pressure, voltage(Na+, K+)
what surrounds the cell and is made up of proteins and lipids?
plasma membrane
what are the diverse structures that perform various metabolic tasks for the cell?
organelles
how is heat generated in the body? how is it increased?
Heat is a byproduct of the breakdown of ATP. Skeletal muscle generates the most. Cellular activity and the use of ATP
increasing cellular activity, muscle activity, increase of thyroid hormone
how does the sodium potassium pump contribute to core body temperature?
uses ATP, breaking phosphate groups releases heat
Explain why positive feedback is more likely than negative feedback to disrupt homeostasis
Going further from the set point
what is a solution that can resist pH change upon the addition of an acidic or basic component?
chemical buffer
what is the foreign matter or stored cell products?
inclusions
what are all of the body fluids not contained in cells?
ECF
what are the 5 factors that affect diffusion rate?
temperature
surface area
molecular weight
permeability
steepness of gradient
