Question Answer
A pt presents to the ICU w/ cognitive impairment. HPI show a recent stroke. F/U CT scans determine commuincating hydrocephalus w/ enlarged ventricular cavities in the brain. The physician recommends a venticular/peritoneal shunt as a possible intervention, if the hydrocephalus doesn't resolve on its own. Which organ system is directly involved in this pt's dx?Nervous
Which common function do the nervous system and endocrine system share?Homeostatic control of body function
Globular proteins, such as anitbodies and enzymes, would be considered: Water soluble (polar)
Two pairs of electrons shared equally between two atoms is called a/an: Double covalent bond
Water inside the lungs has a natural affinity toward itself, also known as 'surface tension'. Which specific bond is responsible for presence of 'surface tension' in water?Hydrogen Bonds
A lipid (fat) molecule does not dissolve into blood plasma, which is mostly composed of water. What characteristic inhibits its solubility? The lipid molecule is non-polar, therefore hydrophobic
A protein that is characterized by the presence of beta-pleated sheets and alpha-helicies, and is fully functional, is called a: Tertiary protein
Catabolism is defined as: The break-down of molecules, which releases energy
Which form of molecular movement does not require ATP? Facilitated diffusion
An Isotonic solution is defined as: A solution which has the same concentration of dissolved particles inside and outside the cell.
V-Snares and T-Snares are directly associated with:Exocytosis
Clatherin proteins are associated with: Endocytosis
Which form of molecular movement uses ATP indirectly?Secondary active transport
If the inside of a cell is considered to be hypotonic, how would you describe the outside of the cellular environment?Hypertonic
Hgb consists of four, tertiary subunits which come together to create a functional protein. What kind of protein is hgb?Quaternary protein
Nucleotides are: The building blocks of DNA & RNA
Facilitated diffusion is defined as: Movement of molecules down their concentration gradient, through a protein channel, w/out the use of ATP
Which components of a cell's cytoskeleton are responsible for transporting contents throughout it's internal structure?Microtubules
How does Phosphorylation energize molecules?Through the release of electrons
Which subatomic particle is responsible for determining the element? Proton
Ionic bonds are created through: Electrical forces between ions
Which cellular organelle is characterized by its capacity to translate mRNA?Rough endoplasmic reticulum
Gene expression: Begins in the nucleus and ends in the cytoplasm
The genetic code is carried in groups of three nucleotides called a: Codon
What is needed to translate mRNA?t-RNA and RIbosomes
AUG on the mRNA is: start codon
The cardiovascular system is responsible for: Transporting waste and nutrients throughout the body
The sagittal plane creates: Right and Left sides of the body
Positive feedback is when: The original stimulus becomes amplified
The abdominopelvic quadrants are primarily referred to by: Clinicians
The lungs are found in the: Pleural cavity
Which cytoskeletal protein structure is responsible for endocytosis, excytosis, and cell movement? Microfilaments
The Golgi is responsible for: Receiving proteins and modifying them to their final form
A nerve cell is surrounded by high concentrations of NA+, which continuously leaks in. How would you describe the movement of NA+?NA+ is moving down its concentration gradient
A red blood cell is placed in a 0% salt solution, which causes it to expand. The solution is described as:Hypotonic to the blood cell
The organelle that is responsible for housing genetic material, and is the "control center of the cell is the:Nucleus
True or False: Ribosomes and tRNA translate the mRNA to protein.True
Can UAG stop a codon?Yes.
