Answer:
Hey mate here's your answer ⤵️
Lemon juice in its natural state is acidic with a pH of about 2, but once metabolized it actually becomes alkaline with a pH well above 7

Answer:
Inhibitor
Explanation:
Enzyme inhibitors are compounds that can interact with the enzyme but don't trigger any biological response. This is what sulfanilamide does. When the enzyme is bound to sulfanilamide, it stops being able to bind PABA, its normal substrate, and so it cannot perform its biological action. In consequence, the entire biosynthetic pathway for folic acid is stopped.
B.
Isotopes is an atom has same number of electrons and protons but different number of neutron.
Answer: 
of NaOH
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydrogen ion concentration.
![pH=-\log [H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%20%5BH%5E%2B%5D)
Putting in the values:
![10.020=-\log[H^+]](https://tex.z-dn.net/?f=10.020%3D-%5Clog%5BH%5E%2B%5D)
![[H^+]=9.55\times 10^{-11}](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D9.55%5Ctimes%2010%5E%7B-11%7D)
![[H^+][OH^-]=10^{-14}](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%5BOH%5E-%5D%3D10%5E%7B-14%7D)
![[OH^-]=\frac{10^{-14}}{9.55\times 10^{-11}}=1.05\times 10^{-4}M](https://tex.z-dn.net/?f=%5BOH%5E-%5D%3D%5Cfrac%7B10%5E%7B-14%7D%7D%7B9.55%5Ctimes%2010%5E%7B-11%7D%7D%3D1.05%5Ctimes%2010%5E%7B-4%7DM)
moles = 
Mass of 
Thus of NaOH is needed to prepare 463 mL of solution with a pH of 10.020
