Interpretation: It should be identified Hydrolysis of ATP.
Concept Introduction:
Proteins: Proteins are
Lipids: Lipids are the important type of compound found in organism.
They are the principle of components of the cell membrane and a repository of chemical energy in the form of fat.
In addition to the some of the chemical messenger called hormones are lipids.
Polar compound tends to be soluble in polar solvent such as water . But nonpolar compound are soluble in non-polar solvent but they tends not to be soluble in organic solvent.
NADH: The NADH is stands for “nicotinamide adenine dinucleotide (NAD)+ Hydrogen(H).
This chemical occurs naturally in the body and plays a role in the chemical process that generates energy people use NADH.

Chemistry & Chemical Reactivity
- When a mixture of hydrogen and bromine is maintained at normal atmospheric pressure and heated above 200. °C in a closed container, the hydrogen and bromine react to form hydrogen bromide and a gas-phase equilibrium is established. Write a balanced chemical equation for the equilibrium reaction. Use bond enthalpies from Table 6.2 ( Sec. 6-6b) to estimate the enthalpy change for the reaction. Based on your answers to parts (a) and (b), which is more important in determining the position of this equilibrium, the entropy effect or the energy effect? In which direction will the equilibrium shift as the temperature increases above 200. °C? Explain. Suppose that the pressure were increased to triple its initial value. In which direction would the equilibrium shift? Why is the equilibrium not established at room temperature?arrow_forward3 Draw labelled energy level diagrams for the following reactions: a S(s) + O₂(g) → SO₂(g) AH = -297 kJ mol-¹ b 6C0₂(aq) + 6H₂O(l) → C6H₁206(aq) + 60₂(g) AH=+2800 kJ mol-¹ C6H₁206arrow_forwardSuppose the following reaction is at equilibrium: PCl3 + Cl2 ⇋ PCl5; (a) Are the equilibrium concentrations of PCl3, Cl2, and PCl5 necessarily equal?
