Metabolic reactions require organic catalysts called?
Metabolic reactions require organic catalysts called enzymes. These enzymes help to speed up chemical reactions within cells by lowering the activation energy needed for the reactions to occur. Each enzyme is specific to a particular reaction or set of reactions.
How could you determine the effect of temperature on the rate of the chemical reaction between baking soda and vinegar?
For this you would need a stopwatch and the ingredients for the reaction. Now take vinegar in a beaker and keep the stopwatch in one hand. take a pinch of baking soda in the other hand. Now drop it in the vinegar solution and simultaneously start the stopwatch. Note the time taken for the bubbling to stop completely. Now raise the temperature and repeat the same experiment. Do this for 5 set of reading by raising the temperature 5 degrees each time. Now do this by decreasing the temperature 5 degrees. Tabulate the data and think about the answer.
What is a reaction in a balancing equation?
In a balanced chemical equation, a reaction is the process of converting reactants into products. Each reactant molecule is transformed into a set of corresponding product molecules according to the stoichiometric coefficients in the balanced equation.
Why are catalysts reaction specific Iethey are different for different chemical reactions How catalyst modifies the rate of a chemical reaction Why don't they take part react in the chemical reaction?
Catalysis reaction are the generic potential energy. Chemical reactions is the process that leads to the transformation of a set chemical.
Why do you want to control the rate of a chemical reaction?
There are several reasons you might want to control the rate of a chemical reaction: A) the reaction occurs very slowly in normal conditions (like rusting) but you want to do it more quickly (like fake antiques). B) the reaction normally occurs quickly, but you want to slow it down so it lasts longer (like in some batteries) C) most reactions can be more or less efficient depending on the reaction rate and other conditions, often (like in engines) you want the reaction rate that will be most efficient under a set of given conditions. D) some reactions might be more difficult to manage unless they are slowed down.
Does temperature affect reaction time?
Temperature can affect the length of time a reaction takes (reaction rate) because atomic and molecular activity are somewhat temperature dependent. Certainly the mobility of molecules, atoms or ions has a temperature component. The fact that something like dynamite may be packed in ice won't prevent an explosion if it is set off, but many, many chemical reactions have reaction rates that are temperature dependent. The applied chemistry of the preparation of food broadly exemplifies this phenomenon. In chemistry, the Arrhenius equation speaks directly to temperature dependence of a reaction. Indeed, temperature is a factor in particle behavior as is set down in Boltzman distribution. Links are provided for some further reading.

What controls the rate of chemical reaction in human body?
The rate of chemical reactions in the human body is primarily controlled by enzymes, which are biological catalysts that help speed up reactions by lowering the activation energy needed for the reaction to occur. Enzymes can be regulated by factors such as temperature, pH, and the presence of inhibitors or activators. Additionally, the concentration of reactants and products in the body can also influence the rate of chemical reactions.
What is a method that could be used to test the effect of temperature on the rate of reaction of a cellulase?
One method could be to set up multiple reaction vessels with the same concentration of cellulase and substrate, but at different temperatures. Measure the rate of reaction by monitoring a specific parameter (e.g., substrate concentration over time) for each reaction vessel. Plotting the data will allow you to observe how temperature affects the rate of reaction of the cellulase.
How do enzymes affect chemical reaction?
Usually enzymes have the role to catalyse a reaction. That means they aren't changed at all, but they influence the mechanism to reduce the activation energy (the energy needed for the reaction). The reaction is therefore performed more easily. To put it very simply: It speeds up a chemical reaction.
Enzymes are examples of?
biological catalysts that speed up chemical reactions by lowering the activation energy needed for the reaction to occur. They are specific in their action, often catalyzing only one type of reaction or a set of closely related reactions.
Why is it useful to designate a standard temperature and pressure?
As you may soon learn in thermodynamics, the reaction rate constant, k, depends on the activation energy, temperature and pressure (if gaseous) of the system. Therefore, to unify reaction rates and rate constants, a standard temperature and pressure (such as STP and SATP) is designated to make sure when one chemist publishes a certain set of results, it could be accurately reproduced using the exact same reaction circumstances.

What are three statements that describe an enzyme?
1. It is not used up and does not change shape in a reaction. 2. It is used to speed up a reaction 3. Will only bind to another molecule as long as the enzyme substrate complex can form(see lock and key theory)
If a temperature increase from 22.0 to 34.0 triples the rate constant for a reaction what is the value of the activation barrier for the reaction?
You can use the Arrhenius equation to solve for the activation energy barrier (Ea). The formula is k = A * exp(-Ea/RT), where k is the rate constant, A is the pre-exponential factor, Ea is the activation energy barrier, R is the gas constant, and T is the temperature in Kelvin. Since the rate constant triples when the temperature increases from 22.0 to 34.0, you can set up two equations using the Arrhenius equation and solve for Ea.

How do you set up a PCR reaction?
To set up a PCR reaction, you mix together DNA template, primers, nucleotides, DNA polymerase, and buffer in a tube. Then, you run the reaction through a series of temperature cycles in a thermal cycler to amplify the DNA.
