A cell was observed under a microscope and found to contain ribosomes, a cell wall, and DNA. Further inspection determined that no phospholipids are present in the cytoplasm of the cell.
Identify the type of cell as plant, animal, bacteria, or not enough information to determine.
What is a bacteria cell because it must not contain any membrane bound organelles.

Of the three main functional groups found on an amino acid, this is the only one that changes based on the amino acid in question.
What is the variable "R" side chain.
200
The two organelles found in plant cell responsible fr the conversion of solar energy into chemical energy in the form of ATP.
What are the...
(1) chloroplast: solar energy --> sugar (chemical energy)
(2) mitochondria: sugar (chemical energy) --> ATP (chemical energy)

The property of water that makes belly flops hurt and allows the basilisk lizard to run on water.
What is surface tension? (I'll also accept cohesion since cohesion causes surface tension)
300
A monomer of lipids that has less than the maximum number of hydrogens due to the presence of a carbon-carbon double bond.
What is an unsaturated fatty acid?
300
A polymer of comprised of 5 amino acids would be called....... and its synthesis would remove ....... many water molecules.
What is a polypeptide and 4 water molecules?

Tay-Sachs disease is a rare genetic disorder that results in progressively deterioration of the central nervous system and ultimately death. Individuals with Tay-Sachs have lost the ability to break down and recycle toxic substances called GM2 ganglioside that build up in the nerve cells. As a result, GM2 ganglioside builds up to toxic levels and kills neurons in the brain and spinal chord.
This organelle is not functioning properly in individuals with Tay-Sachs.
What is the lysosome?
300
The number of horcruxes killed using basilisk venom.
What are 5?

This would most likely occur to the pepsin enzyme (found primarily in you stomach) if it were to enter the small intestine where the pH is approximately 8.
What is it would denature?
400
Your Liver uses this general chemical process when storing excess blood glucose by combining them as polysaccharide called glycogen.
What is dehydration synthesis?
400
Name a disaccharide and the monosaccharide from which it is made.
What are:
Sucrose (glucose and fructose)
Maltose (glucose and glucose)
Lactose (glucose and galactose)
400
Globular proteins that speed up a chemical reaction by lowering the activation energy needed for that reaction to occur.
What are enzymes?
400
Organelle described brilliantly as if "The post office received your mail, opened it, reorganized and combined it into one package, and then shipped it back out!"
What is the Golgi apparatus?

Of the 19 African countries completely south of the equator, these would be the first and last alphabetically.
What are Angola and Zimbabwe?

The type of property described by this fact:
Organelles are not living yet several organelles working together creates a living cell.
What is an emergent property?
500
Any molecules, such as Bicarbonate (HCO3-), that can prevent fluctuations of pH. (example below)
(acidic conditions: H+ + HCO3- --> H2CO3)
(basic conditions: OH- + HCO3- --> CO32- + H2O)
What is a buffer?
500
Name three specific lipids and provide the function of each.
What are:
(1) Triglycerides - Storage of energy as fats, thermal insulaiton
(2) Phospholipids - Make up the cell membrane, regulates what enters the cell
(3) Cholesterol - maintains the integrity of the cell membrane in animals and is the building block for steroid hormones
(4) Wax and oil - hydrophobic barrier that prevents water from getting where it shouldn't. Ex. human skin, leaf epidermis, and feathers of aquatic birds like ducks.

Sulfanilamide is an antibiotic molecule that binds to the active site of the DHPS enzyme in bacteria preventing the substrate (PABA) from binding. This prevents production of folic acid, an essential nutrient that bacteria must synthesize because they do not have a transporter for it. Without folic acid, bacteria cannot grow and divide.
Based on its function, Sulfanilamide can be considered this type of enzyme related molecule.
What is a competitive inhibitor?
500
Three structures that maintain the shape and structure of the cells. Two in a plant cell and one in an animal cell.
What are the central vacuole and cell wall (plant) and cytoskeleton (animal).
