Answer:
In the given example, malonic acid is the competitive inhibitor of succinate.
Explanation:
- When a substance diminishes the velocity of an enzyme catalyzed reaction then it is called inhibitor.
- These inhibitors can bind to enzyme in a reversible or irreversible fashion.
- Reversible inhibitor binds to enzyme by non-covalent bonds.
- There are two types of enzyme inhibition: Competitive and non-competitive.
- Competitive inhibition: We use the term competitive if the inhibitor binds to enzyme reversibly at the same site as substrate would bind.
- Here in this example, both succinate and malonic acid have same binding site on enzyme i.e the active site. Since both can bind to the same site, inhibitor competes with the substrate for that site.
- By increasing the concentration of substrate, we can reverse the effect of competitive inhibitor.
- At a sufficiently high concentration of substrate, V-max can be achieved for the reaction. In the Michaelis-Mentens curve we can observe increase in the Km value in the presence of competitive inhibitor.
Answer:
The roman numerals in blue are the labels I will write below.
Explanation:
i. lone pair of electrons on oxygen atom
ii. covalent bond between oxygen and hydrogen
iii. partial charges that are due to oxygen's high electronegativity. Oxgen will pull the pair of electrons in the covalent bond towards itself and that obtaining a partial negative charge, while hydrogen obtains a partial positive charge.
iv. hydrogen bonds between partially negative oxygen and partially positive hydrogen.
PS. EACH WATER MOLECULE CAN MAKE UP TO 4 HYDROGEN BONDS. ONE WITH EACH HYDROGEN AND TWO FOR EACH ELECTRON LONE PAIR ON OXYGEN. (refer to the middle water molecule in the diagram)
