Explanation:
Amino acids capable of forming hydrogen bonds with a lysine residue in a protein typically have functional groups that can participate in hydrogen bonding. Lysine has a positively charged amino group (NH3+) as part of its side chain. Therefore, an amino acid with a functional group capable of forming a hydrogen bond with this amino group could interact with lysine.
One such amino acid is aspartic acid (Asp or D). Aspartic acid has a negatively charged carboxyl group (COO-) in its side chain. This carboxyl group can form hydrogen bonds with the positively charged amino group of lysine (NH3+), creating a stable interaction within the protein structure.
So, aspartic acid (Asp) is an example of an amino acid capable of forming hydrogen bonds with a lysine residue in a protein. This interaction contributes to the overall stability and structure of the protein.
b. the reaction rate does not change.
c. the reaction rate increases.
d. the equilibrium shifts.
In liquid water, an equilibrium exists between H2O(ℓ) molecules, H+(aq) ions, and OH−(aq) ions. A person experiencing acid indigestion after drinking tomato juice can ingest milk of magnesia to reduce the acidity of the stomach contents. Tomato juice has a pH value of 4. Milk of magnesia, a mixture of magnesium hydroxide and water, has a pH value of 10. The balanced chemical equation is 2H2 + O2 = 2H2O.
Explanation:
isotope are atom of the same elements with the same number of protons, electron and different number of neutrons.
a.endothermic
b.exothermic
c. both endothermic and exothermic
d. neither endothermic nor exothermic
2. The total amount of energy before and after a chemical reaction is the same. Thus, energy is
a. created
b. destroyed
c. conserved
d. the same as mass
1. Answer;
- Exothermic reaction
Explanation;
-Exothermic reactions are types of chemical reactions in which heat energy is released to the surroundings. Since enthalpy change is the difference between the energy of products an that of reactants. It means that in an exothermic reaction the energy of products is less than that of products. In this case an energy of 315kJ is released to the surroundings.
2. Answer;
Conserved
-The total amount of energy before and after a chemical reaction is the same. Thus, energy is conserved.
Explanation;
-According to the law of conservation of energy, energy is neither created nor destroyed. Energy may change form during a chemical reaction. For example, energy may change form from chemical energy to heat energy when gas burns in a furnace. However, the exact amount of energy remains after the reaction as before, which is true for all chemical reactions.
