UCONN ECE Biology Final exam with answers
Ionic - ....🔰VERIFIED ANSWERS.... ✔✔Ionic bonding is the complete
transfer of valence electron(s) between atoms.
In ionic bonds, the metal loses electrons to become a positively charged cation,
whereas the nonmetal accepts those electrons to become a negatively charged
anion.
Ionic bonds require an electron donor, often a metal, and an electron acceptor,
a nonmetal
Ex. Sodium Chloride (NaCl)
Covalent - ....🔰VERIFIED ANSWERS.... ✔✔Covalent bonding is the sharing
of electrons between atoms.
This type of bonding occurs between two atoms of the same element or of
elements close to each other in the periodic table.
Ex. Water (H2O)
Hydrogen - ....🔰VERIFIED ANSWERS.... ✔✔Weak bond between a slightly
positive atom of a polar covalent bond attracted to a slightly negative atom in a
polar covalent bond
,Ex. bond between water molecules
Van der Waals - ....🔰VERIFIED ANSWERS.... ✔✔Weak attractions that allow
transient partial charges
Ex. diatomics (HH)
What is allosteric regulation and how does it work? - ....🔰VERIFIED
ANSWERS.... ✔✔Regulating the availability of the enzymes active site
Can change structurally (inhibit) or hold open for better binding (enable)
What factors affect how permeable a phospholipid membrane is to a molecule?
- ....🔰VERIFIED ANSWERS.... ✔✔- Change in temp
- pH
- Number of saturated and unsaturated fatty acid tails
- Number of proteins
What are the reactants/products of glycolysis? - ....🔰VERIFIED ANSWERS....
✔✔R: 1 glucose molecule
P: 2 pyruvate
2 Net ATP
2 NADH
, What is the difference between the energy investment phase and the energy
payoff phase? - ....🔰VERIFIED ANSWERS.... ✔✔Investment: 2 ATP are
needed to initiate the first half of reaction
Payoff: Creating 4 ATP by substrate level phosphorylation
Why is the energy investment phase needed? - ....🔰VERIFIED ANSWERS....
✔✔To get the reactions started
Amino Acid - ....🔰VERIFIED ANSWERS.... ✔✔R group
OH group
H
Lipid - ....🔰VERIFIED ANSWERS.... ✔✔Look for sugar backbone
