Catalysts and Catalysis

Pt (platinum) is used as a catalyst because it has a high catalytic activity and stability in various chemical reactions. Its ability to facilitate reactions by providing an active surface for molecules to interact and break or form bonds makes it an ideal catalyst for many industrial processes. Additionally, Pt is resistant to corrosion and high temperatures, allowing it to maintain its catalytic activity over prolonged periods.

Candle burns with a yellow flame because its an incomplete combustion. The temperature of the flame also relates to its colour and also the trace metal ions present will influence the flame colour.

Catalysts lower the activation energy required for a reaction to take place by providing an alternative reaction pathway. This allows the reaction to proceed more quickly and with less energy input. The overall energy change of the reaction remains the same, but the rate of the reaction is increased.

well a catalyst is something that speeds up a reaction so an enzyme no?

It means decreasing the efficiency of the catalyst, and slowing down the reaction. The chemicals used for this are called Inhibitors, although it may not contain any poisons or toxic chemicals

Living things rely on enzymes to carry out essential chemical reactions in their bodies. Without enzymes, these reactions would occur too slowly or not at all, leading to the inability to survive. Therefore, living things cannot survive without enzymes.

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.

Digestive enzymes are natural substances produced by the body to help break down food for absorption. Papaya enzymes specifically refer to a type of enzyme found in papaya fruit called papain, which can also aid in digestion by breaking down proteins. While both can support digestion, papaya enzymes are derived from papaya fruit, whereas digestive enzymes can come from various sources and assist in breaking down different types of nutrients.

Enzyme are not producing proteins but they catalyses the steps in proteins synthesis. Proteins are produced in ribosomes by amino acids and RNA molecules such as tRNA and mRNA. Enzyme such as peptidyl synthetase catalyse the prptide bond formation between amino acids.

Enzymes are typically named based on the substrate they act on, with the suffix -ase added to indicate their enzymatic function. For example, an enzyme that breaks down lactose is called lactase. Sometimes enzymes are also named based on their function or the organism they are derived from.

In jam, enzymes are typically not present in significant amounts. However, depending on the ingredients used, some natural enzymes from fruits such as pectinase (breaks down pectin in fruits) may be present. Commercially produced jam may be processed at high temperatures to deactivate any enzymes present.

Enzymes are proteins that act as catalysts in mediating and speeding specific chemical reactions in biological systems. They lower the activation energy required for a reaction to occur, making the reaction proceed faster. Enzymes are highly specific, each one catalyzing a particular reaction or a group of related reactions.

A reactant that binds to a catalyst is known as a substrate. Substrates bind to the active site of the catalyst, where the chemical reaction takes place. This binding lowers the activation energy required for the reaction to occur.

Yeh, Its An Active Enzyme, i Think Its Mostly Active In Heat; Not Too Sure Though

But It Is Definatley Active :)

Enzymes are typically recycled in living systems by being released from their substrate and remaining unchanged after catalyzing a reaction. They can then go on to catalyze more reactions. In some cases, enzymes may be modified or degraded after use and their components reused to make new enzymes.

A biological catalyst protein is called an enzyme. Enzymes speed up chemical reactions in living organisms by lowering the activation energy required for the reaction to occur.

Yes, MnO2 can act as a catalyst in certain reactions. It is commonly used as an oxidizing agent in organic synthesis reactions and can promote reactions by providing an alternative pathway with lower activation energy.

You can't hear an En Zyme, but you CAN hear a Hor Mone!

An enzyme is a protein substance produced in living cells,influencing chemical reactions within plants or animals without being changed itself. Functioning as organic catalysts, enzymes help break down food so that it can be digested. The enzyme pepsin hydrolyses protein chains in the mammalian stomach to initiate digestion A hormone is a substance formed in the endocrine glands, entering the blood stream and affecting or controlling the activity of some organ, or of cells or tissues. Adrenalin and insulin are hormones. In plants hormones are carried in the protoplasm and act similarly. The difference between an enzyme and a hormone is due to the purpose they are designed to serve. Hormones control aspects of growth and metabolism such as the breaking of the voice and the development of musculature during puberty in males; and the regulation of the menstrual cycle in females. Enzymes mediate all reactions in cells, their structure and synthesis being determined by DNA.

THat is a good question. Currently carbohydrates can not serve as catalyst and would be a great discovery if they did. Currently proteins, DNA, and RNA only have catalystic properties.

Catalyzed reaction has a lower activation energy because there is an enzyme present in the reaction.

Uncatalyzed reaction has a higher activation energy because there is no enzyme present in the reaction.

Enzymes speed up chemical reactions by lowering the activation energy. The activation energy is the amount of energy needed to start a reaction and if this is lowered the reaction can occur more rapidly.

A cofactor refers to a macromolecule that attaches to an enzyme to assist in catalysis. This can be a metal ion or a coenzyme.

Enzymes are the most common type of catalyst that affect biochemical reactions. They are proteins that facilitate specific chemical reactions in living organisms, speeding up the reaction without being consumed in the process.
