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.

Enzymes

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.

• In the chemical industry and the industrial research, catalysis play an important role.
• The different catalysts are in constant development to fulfill economic, political and environmental demands.
• When using a catalyst it is possible to replace a polluting chemical reaction with a more environmental friendly alternative. Today, and in the future this can be vital for the chemical industry.
• The catalysts could help in accelerating chemical reactions and/or making it possible at lower temperatures.

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.

Enzyme

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.

See the Web Links to the left of this answer for more information.

They lower the activation energy required for the reactions to take place

A catalyst provides a reaction pathway with a lower activation energy and so directs the reaction one specific way or accelerates the reaction. An inhibitor blocks a reaction path and so prevents a product or slows down the reaction.

A catalyst decreases the threshold energy for a chemical reaction.

A catalyst decreases energy required for two particles to react.

A catalyst lowers the amount of energy needed to reach the transition state.
