All first row/period transition metals, iron included, are good catalysts.
They provide a surface on which the reactants can briefly adhere, thereby slightly altering the electronic energies/ arrangements. This allows the other reactant to react quicker, thereby the electronic arrangements change again and the new molecule detaches from the catalytic surface.
NB
Catalysrs speed up a reaction. and Inhibitors slow down a reaction.
YES!!! TRue.
Inhibitors decrease the rate of reaction, especially if ther reaction is too fast.
Enzymes are very specific catalysts. They aid a reaction to go forward, but only at a very specific temperature and pH environment.
Specificity: Enzymes are highly specific in their actions. Each enzyme typically catalyzes a particular chemical reaction or a limited set of reactions. This specificity can hinder their use in some industrial applications where a broader range of reactions may be desired.
The base of a microscope is the bottom part of the microscope that provides stability and support. It typically houses the light source, such as a lamp or a mirror, and also contains the power switch and controls for adjusting the brightness and intensity of the light, as well as other possible features such as a power supply or a battery compartment. The base is essential for maintaining the overall balance and stability of the microscope during use.
Vitamin B6, also known as pyridoxal phosphate (PLP), binds to enzymes and functions as a coenzyme. It plays a vital role in various biochemical reactions, acting as a catalyst for over 100 enzymatic reactions in the body. Some of these reactions include the metabolism of amino acids, production of neurotransmitters, and synthesis of hemoglobin.
The green colored catalyst in a plant cell is called chlorophyll. It plays a crucial role in photosynthesis, capturing light energy and converting it into chemical energy to fuel the plant's metabolic processes.
Yes, potatoes contain various oxidases and peroxidases. But I'd suggest taking a look at your bio textbook or lab info, or listening to your teacher.
is because it speeds up the process. In orded to get the product in a shorter time.
The correct answer is a simple one: The system is unaffected by a catalyst in a system in equilibrium.
the reaction of one functional group in the presence of another same or different functional group
Most enzymes are proteins, yes. However, the statement (used some number of years ago) that all enzymes are proteins is false. There are a few (but important) exceptions to that generalization.
One property of transition metals is that all elements and compounds in transition metals act as a catalyst ( speeds up chemical reactions. )

I think it frees itself from the product and is ready to be reused.
but all catalysts aren't enzymes...
speed up chemical reaction because of the lowered activation energy
A catalyst is a substance which speeds up the rate of reaction. After the reaction it remain chemically unchanged. It does NOT affect the position of equilibrium. There can also be negative or "poisoned" catalysts as in Rosenmunds reaction.
Just about every reaction in our bodies is regulated by an enzyme. The word enzyme is just another word for catalyst.
Enzymes help in digestion of food by catalyzing the biochemcal reactions between food molecules and chemicals that helps in digestion.
Enzymes speed up the biochemical reactions and act as catalysts.
No, not at all. No, not at all. No, not at all.

1.Are there any differences between the calculated density and the experimental density of a substance? If so, why?
Yes, it would bubble because the bubbles are the result of the breakdown of two hydrogen peroxide molecules into oxygen and two water molecules.
It decreases the activation energy, or the energy barrier the reactants must go through to form products. This is the same thing as the energy of the transition state.
By decreasing the activation energy necessary for the reaction to occur, more reactants are able to form products since not as much energy is needed.
