What are the major elements in proteins?
|
Carbon, hydrogen, nitrogen, oxygen, and sulfur
|
What are the major elements in nucleic acids?
|
Carbon, hydrogen, nitrogen, oxygen, phosphorous
|
What are the major functional categories of proteins?
|
Enzymes, transport, storage, membranes, movement, signaling (incl. antibodies and neurotransmitters), and connective tissue.
|
What type of reaction occurs when two amino acids attach? What is the byproduct?
|
Dehydration synthesis; water.
|
What is the general chemical formula of all fatty acids?
|
CH3(CH2)nCOOH where n is an even number between 12 and 24.
|
What are glycerides? What are they made of?
|
They are esters composed of glycerol (CH 2 (OH)CH(OH)CH 2 (OH)) plus three fatty acid chains.
|
What is emulsification (in regard to phospholipids)?
|
Basically, how detergents work; amphipathic (hydrophobic + hydrophilic) lipids surround a fat droplet and break it in to smaller particles.
|
What lipid steroid is commonly found in cell membranes?
|
Cholesterol
|
What are the main structural constituents of a steroid?
|
Three fused six-membered rings and one five-membered ring.
|
What kind of bonds join carbohydrates? What are the two types?
|
Glycosidic bonds, which bridge from one sugar to another with an oxygen in between.
Alpha linkage = kinks (ex. glycogen and starch)Wh Beta linkage = straight chain (ex: cellulose) |
What are the three main structural components of nucleic acids?
|
A 2-or-3-ring nitrogenous base, a sugar, and a phosphate group.
|
What is the net reaction of glycolysis?
|
Glucose + 2ADP + 2Pi + 2NAD+ ----> 2Pyruvate + 2ATP + 2NADH + 2H+ + 2H2O
|
What are the three ways pyruvate can be reduced under anaerobic conditions?
|
Fermentation, alcohol fermentation, and lactic acid fermentation.
|
What is the net gain of ATP in each of the three main stages of eukaryotic ATP production?
|
+6 from glycolysis, +6 from pyruvate decarboxylation, +24 from the citric acid cycle.
Total: +36 |
What is the overall net reaction of photosynthesis?
|
6CO2 + 12H2O + light ---> C6H12O6 + 6O2 + 6H2O
