Chemistry & Water
What is the property of an acidic vs basic solution
Acids have higher H+ concentrations & bases have higher OH- concentrations
The twisting of the string of amino acids into an alpha-helix or pleated sheet.
What is a secondary structure of a protein?
Cells where you can find cell walls.
Prokaryotic & plant cells
Function of cholesterol in the plasma membrane
What is to keep the plasma membrane from becoming too fluid or too stiff. (maintains fluidity)
The mechanism by which enzymes work
What is the number of neutrons of Chlorine if the atomic mass is 36. (atomic number =17)
What is 19?
a molecule with a polar and nonpolar end. phospholipid
function of ribosomes
what is protein synthesis?
Compare and contrast passive and active transport
Active transport requires ATP and moves substances against their concentration gradient. Passive transport moves substances from high concentration to low concentration.
Name the enzyme: attaches to an allosteric site, changing the shape of the active site.
What is a noncompetitive inhibitor?
Name the bond type: unequal sharing of electrons between covalently bonded oxygen (or N or F) and hydrogen atoms.
What is Hydrogen Bonds?
The removal of -H and -OH from monomers to join the monomers into a polymer, and form water.
Gangliosides (lipids found in membrane neurons) are most likely produced in which organelle?
What is Smooth ER?
what happens to a cell that is put in a hypotonic solution?
the cell bursts, and the water moves into the cell
reaction that is not spontaneous & requires energy
what is an endergonic reaction?
name 3 properties of water
What is cohesion, adhesion, surface tension, density, solvent properties & heat capacity?
what is the central carbon of a protein surrounded by?
- hydrogen
-amino group
- carboxyl group
-R group
Name of the thing that walks along the cytoskeleton tracks to transport vesicles or organelles.
What is a motor protein?
name the 3 types of gated channels
what is ligand, voltage & mechanical?
Reaction where the transfer of energy is due to the loss of an electron
What property of carbon makes it so versatile? and why?
What is a nucleic acid made of and give an example (of a larger structure it could build into)
Explain endosymbiotic theory
the theory that mitochondria and chloroplasts were once independent bacteria cells but formed a symbiotic relationship with another cell to create a eukaryotic cell.
Explain the order of the secretory pathway.
1. protein is put into RER as ribosomes make its
2. RER -> vesicles to Golgi to be modified
3. Vesicles buds off Golgi with protein
4. vesicle fuses to plasma membrane -- secreted (exocytosis) or fuse to membrane
The breakdown of complex molecules into simpler compounds, releasing energy
What is a catabolic pathway?
