For an extra 100 points each: name the other two functions!
For an extra 100 points: what is the most basic unit of carbohydrates? (bonus if you can name the main example!!)
The main function is quick energy production. Does this by breaking down its most basic units called monosaccharides (specifically glucose). (other functions are 'labeling cells' and forming the backbone of DNA/RNA)
What is the difference between cytosol and cytoplasm?
Cytoplasm is cytosol + organelles (EXCEPT the nucleus!)
What 'organelle' is responsible for breaking down non-needed proteins in the cell?
For an extra 100 points each: what are the other two members of the 'clean up crew'?
Proteasomes (the other two are peroxisomes and lysosomes)
A student is asked to show correct anatomical position. They stand up straight, hands facing posteriorly, and feet are slightly separated. Are they in the correct position? Why or Why not?
Not due to hands facing posteriorly (aka backwards; hands should be facing forward)
True or False: Homeostasis is a stagnant process.
False (homeostasis is very dynamic because the body changes as it interacts with the environment!)
Two molecules are bounded together and they are sharing a molecule. Although they are sharing, one is pulling the electron more than the other. What type of bond is this?
For an extra 100 points: what is an example of a molecule that uses this bond?
Polar bond (big example: water!!)
What are the weakest bonds found in our body?
For an extra 100 points: Why are these the weakest?
Hydrogen bonds (only have an 'attraction' so no electrons are shared or exchanged!)
About 95 percent of the energy needed to keep a cell alive and functioning is generated by what structure?
For an extra 200 points: When this structure generates energy, it changes ATP into ADP. Is this a catabolic or anabolic process?
Mitochondria (breaks ATP (adenosine TRIphosphate) into ADP (andeosine DIphosphate) to create energy)
How is resting membrane potential calculated?
For an extra 100 points: There is a major protein that's only function is to regulate the RMP. What is this protein called?
Electric charge from outside plus electric charge from the inside (regulated by sodium-potassium pump!)
A patient came in complaining about stomach pain. After feeling the area, the doctors concluded that the area is focused above his stomach. What abdominopelvic region is affected in this situation?
Epigastric Reigon
What organ system deals with collecting fluid and controls our immune system?
For an extra 400 points: name the other 10 systems.
Lymphatic System
What reaction takes out water to combine two molecules?
For an extra 100 points: is this process anabolic or catabolic and why?
For an extra 100 points: name the process that reverses this reaction.
Dehydration synthesis (anabolic reaction; opposite reaction is hydrolysis)
For an extra 100 points: name a special characteristic of phospholipids.
For an extra 100 points: There is another kind of lipid that is related to phospholipids. What other kind of lipid is seen with phospholipids in its function?
Make the plasma membrane and separate inside of cell from the outside (they are amphiphilic; steroids (cholesterol!!) are specifically seen with filling in gaps in the plasma membrane)
What is the main function of tight junctions?
For an extra 100 points: These can be related to a certain necessary life function. What NLF is directly related to this type of cell junction?
For an extra 100 points each: name the other two cell junctions with their functions.
Keep things separated (related to function of separation)
Other cell junctions are desmosomes (keep cells together or 'anchor') and gap junctions (communication)
Where does the process of transcription occur?
For an extra 100 points: The process starts with what? What does it end with?
In nucleus (starts with DNA; ends with mRNA)
True or False: The popliteal area is distal to the tarsal area.
False (Popliteal (knee) is proximal to the tarsal (ankle) area)
A student claims a person with left-sided chest pain must have pain in the left hypochondriac region. Is the student correct? Why or why not?
They are incorrect because the abdominopelvic regions cannot be used to describe areas above the diaphragm.
A patient comes in and they are vomiting excessively. After doing a blood test, it was found that their blood pH was 8. Describe the state of the blood in terms of pH.
For an extra 100 points: what is the normal pH for blood?
The blood is basic (normal blood ~7.4)
A protein has had its shape change due to hydrogen bonds. Now instead of having a beta-sheet form, it now has folded together into almost a ball shape. What level of protein structure is this an example of?
For an extra 100 points: what is an important characteristic of proteins at this level?
Tertiary level (the most common protein level in the body!)
