Catalysts and Catalysis

Everyone, from birth and even before, produces enzymes that allow us to digest and metabolyze and to perform the basic, chemical level activities that are needed for life.

The question you MIGHT have been wanting to ask is, "what age group has active HORMONES?" Typically, sex hormones start to become active at about the time that secondary sex characteristics start to develop. For boys, it's hair on the legs, beard, pubic hair, voice change and other changes that start to show up like pimples. For girls it's much the same, but of course girls don't get the beard, they typically have breasts start to develop during that time. That's went he sex hormones START. If you're normal and nothing goes wrong, sex hormones will be active for the rest of your life in one degree or another. It's just that during puberty (when the sex hormones start and some argue are most active) there seems to be a "newly discovered" aspect of life that causes teens to act like it hasn't happened to anyone before them.

Maturity and experience teach us how to live with those hormones.

It depends on the reaction you're trying to affect. Caffeine affects certain reactions, as does alcohol and sleeping pills. Ice slows quite a number of reactions, and lowering the body temperature can certainly affect almost all bodily reactions, since the human body is an chemical/electrical organism. Your Thyroid gland produces a hormone that speeds reactions and a problem with your Thyroid gland will certainly cause problems that are quite diverse. Clinical depression can also slow reaction rate. Exercises speed many reactions and do it in a far more healthy way than do chemicals. To get a more specific answer, you'll need to ask a more specific question.

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.

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.

• 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.

Enzymes are biological catalysts that are specific to their substrates, while catalysts in general can be either biological or chemical and are not necessarily specific. Enzymes are typically proteins that have specific active sites for their substrates, allowing for precise control over chemical reactions in biological systems. Non-enzymatic catalysts can also speed up reactions, but they may not exhibit the specificity or efficiency of enzymes.

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

A catalyst is a substance that increases the rate of a chemical reaction by lowering the activation energy without being consumed in the process. An inhibitor, on the other hand, is a substance that decreases the rate of a chemical reaction by interfering with the reaction steps or blocking a catalyst.

At low substrate concentrations, the rate of enzyme activity is proportional to substrate concentration. The rate eventually reaches a maximum at high substrate concentrations as the active sites become saturated.

Cooling: When an enzyme is cooled, the activity is only slowed down.

Heating: If an enzyme is overheated, it is known as a denatured enzyme. It changes shape to due the break down of it, and will no longer be able to bond with the substrate.

Stop relying on others to help you out on your homework. Read your book

The larger the ionic radius, the more reactive the cation because the outermost electron is held more loosely and therefore more easily lost. In case of anions, the larger the ionic radius, the smaller the force of attraction between the nucleus and the coming -ve electron, so it becomes less reactive.

The coagulase enzyme activates prothrombin, which causes fibrin formation around the bacteria (ie Staph aureus), protecting it from phagocytosis. Of all 3 pathogenic staphylococcal species, only Staph aureus is coagulase positive.

yeap, a heat catalyst

Hepatocytes. "Hepato" refers to anything related to the liver.

the amylase degrades the starch

MnO2 is the chemical formula(there is no equation). The compound is called manganese oxide and manganese(IV) oxide by IUPAC. Wikipedia calls it manganese dioxide.

Here is one of those Short yet Sharp Answers: While all Enzymes are Catalysts not all Catalysts are Enzymes.

What they do share is 'the ability to be a catalyst for a chemical reaction'. Enzymes happen to specialize in Biochemical reactions.

We became catalyst when we visit to in-laws home.

it speeds up the process

:)

a catalyst lowers the activation energy for both the forward and reverse reaction. however, it does not change the potential energy of the reactants or products. it also does not affect the heat of reaction (delta h)

Silver nanoparticles are used in antibacterial technology embedded in refrigerators, washing machines, air coolers, air conditioners, vacuum cleaners and air purifiers. This helps in blocking transmission of airborne diseases in humans and increases safety of health.
