Isopropyl alcohol is mixed with water to produce a 35.0 % (v/v) alcohol solution. How many milliliters of each component are pre
PilotLPTM [1.2K]

229.25 mL of isopropyl alcohol

425.75 mL of water

Explanation:

Knowing that the solution have a 35.0 % (v/v) isopropyl alcohol in water, we can calculate the volume of each component as following.

volume of  isopropyl alcohol = (35/100) × solution volume

volume of  isopropyl alcohol = 0.35 × 655 mL = 229.25 mL

Now, knowing the volume of isopropyl alcohol we can determine the volume of water.

volume of the solution = volume of isopropyl alcohol + volume of water

volume of water = volume of the solution - volume of isopropyl alcohol

volume of water = 655 mL - 229.25 mL = 425.75 mL

BIOCHEMISTRY HELP! You and a lab partner are performing on several molecular analogs to determine Km. One is a substrate analog,
Alina [70]

Answer:

Michaelis constant is known as km which is the substrate concentration that encourages the compound to work at half maximum velocity represented by Vmax/2. Michaelis constant is inversely related to the substrate and the affinity of the enzyme.  

Induced fit model: The premise of the purported induced fit hypothesis, which expresses that the attachment or association of a substrate or some other atom to an enzyme causes an adjustment to the enzyme in order to fit or restrain its activity.  

In substrate, analog Km or Michaelis constant will be high as the substrate will stay because of analogs inhibit activity.

In the transitional state, analog Km will be in the middle of the substrate and product analogs. Progress state analogs are synthetic mixes with a structure catalyzed reaction that looks like the progressing condition of a substrate atom in a compound enzyme.  

In item simple thus Km is the least.  

0.0013 M = product ananlog,

0.025 M=Transition state, and

0.0045 M = Substrate analog
