The most abundant compound that can be found in the sea apart from water is the sodium chloride (NaCl). This is why we are able to retrieve table salt, which also comes in the same formula, from the sea. When sodium chloride dissociates into its ions, the two ions would be Na+ and Cl- which are called sodium ion and chloride.
Answer:
<em>Endothermic reactions: separation of solute molecules , separation of solvent molecules</em>
<em>Exothermic: formation of solute-solvent interactions</em>
Explanation:
An endothermic reaction can be described as a reaction which requires energy. Usually, the energy is taken in the form of heat from the environment. For example: the separation of solute and solvent molecules.
An exothermic reaction can be described as a reaction in which energy is released during a reaction. For example, a solute and a solvent reaction. Energy is usually released in the form of heat during an exothermic process.
Answer:
thermodynamically unstable but kinetically stable.
Explanation:
The complete question is as follows:
Under physiological conditions, peptide bond formation and degradation both require enzymes, but only formation requires coupling to GTP hydrolysis. Based on this information, peptide bonds under physiological conditions are:
A. both thermodynamically and kinetically stable.
B.thermodynamically unstable but kinetically stable.
C.thermodynamically stable but kinetically unstable.
D. both thermodynamically and kinetically unstable.
- The term thermodynamically unstable refers to the fact that the peptide bonds are prone to breakage under physiological conditions.
- The reason why one can conclude the thermodynamic instability of the peptide bonds under physiological condition is that there is a need for a source of energy i.e. GTP hydrolysis for the formation of the peptide bond.
- The fact that the breakage of peptide does not require any input of energy but the only formation does confirms the fact that under physiological conditions they are thermodynamically unstable.
- Even though they are thermodynamically unstable, they are kinetically stable because both the formation and degradation require enzymes.
- The function of enzymes is to decrease the activation energy and hence, increase the rate of reaction. This means that if the enzymes are absent the rate of breakage of peptide bonds would be really slow this points out to the fact that they are kinetically stable under physiological conditions.
Answer:
cells make up tissues, which make up organs. organs make up organ systems which make up organisms
