The HMG-CoA Reductase reaction is rate-limiting for cholesterol synthesis.
The rate-limiting enzyme of the urea cycle is carbamoyl phosphate synthetase I, which catalyzes the first step in the pathway. This enzyme is activated by N-acetylglutamate, which serves as a regulatory molecule in response to the levels of amino acids.

A rate-governed or rate-limiting process is a process in which there are several steps; however, the rate of one or more steps is much slower than all the others. The rates of the previous steps and following steps are assuming to be infinite, and the rate of the process only depends on the rate-limiting step(s).
It inhibits the rate-limiting enzyme (HMG-CoA reductase) in the multi-step pathway of cholesterol synthesis, in the liver.
Chemical reactions involve the breaking and forming of bonds, and the rate at which this happens can vary widely. Some reactions, like rusting, can be very slow, taking years to noticeably occur. However, reactions can be sped up by changing conditions like temperature and pressure.
The molecularity of the rate-controlling step may not necessarily be the same as the overall reaction order. The rate-controlling step is determined by the slowest step in a reaction mechanism, while the overall reaction order is the sum of the individual reactant concentrations in the rate law equation. It is possible for the molecularity of the rate-controlling step to influence the overall reaction order, but they are not always directly correlated.
The first step in determining a limiting reactant is to write a balanced chemical equation for the reaction. This will allow you to compare the stoichiometry of the reactants and products and determine which reactant limits the amount of product that can be formed.
Depends on how many amps you are pumping through it on the limiting leg. As long as you don't exceed the limiting leg rating, then, no.
Omitting the step for digesting the precipitate could lead to inaccurate measurement of the limiting reactant in the salt mixture. The presence of undigested precipitate could interfere with the analysis, resulting in an incorrect determination of the percent limiting reactant. This could lead to erroneous conclusions about the composition of the salt mixture.
Step 1. Find limiting agent (g of H2 / amu) and (g of Cl2 / amu) Cl2 is less mole so it is limiting Step 2. Find the ratio (1:2) 1H + 1Cl = 2 HCl Step 3 mole of limiting x ratio (2) x amu of HCl Source Mastering Chemistry
