Enzymes speed up reactions by lowering the activation energy of the reaction concerned. The enzyme creates a lower energy pathway than if the enzyme wasn't there. For example, hydrogen peroxide, H2O2, decomposes when it gets warmer to H2O(l) and O2(g). However, this process takes a long time normally. The enzyme catalyse allows the above reaction to occur much faster at a lower temperature.
What else can I help you with?
What proteins are vital living thing because they speed up chemical reactions by up to trillion times?
Enzymes are proteins that are vital to living organisms because they act as biological catalysts, speeding up chemical reactions by up to trillions of times. They lower the activation energy required for reactions to occur, making them essential for the efficient functioning of various cellular processes.
What are enzymes and what makes them up?
Globular proteins which catalize bio chemical reactions are called proteins.
What are the most common catalysts in living organisms?
The most common catalysts in living organisms are enzymes. Enzymes are proteins that speed up chemical reactions in cells by lowering the activation energy needed for the reactions to occur. They are specific to particular substrates and play essential roles in metabolism, growth, and other biological processes.
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.
What are the chemical reactions in which enzymes are involved?
Enzymes are involved in a wide variety of chemical reactions in living organisms, including breaking down food molecules into energy (such as in digestion), building new molecules (such as DNA replication), and facilitating cellular processes (such as metabolism). Enzymes function by lowering the activation energy required for a reaction to occur, thereby increasing the rate of the reaction without being consumed themselves.
Are bio-catalysts always proteins?
There are a few RNA catalysts are known, but the majority is only proteins. Biochemical reactions are speed by enzymes by lowering the activation energy. Enzymes like other proteins are coded in DNA.
Why are enzymes needed to control chemical reactions with cells?
enzymes are needed to control chemical reactions within cells because the enzymes acts like catalysts. They basically speed up the reactions within the body, and within the cells, so there fore they help the body maintain its internal environment (homeostasis).-Grade 12 Bio student(exact question came on a handout :P)
In a bio-chemical reaction what are the bio-molecules which are not consumed yet their presence is required?
In every biochemical reaction in the body, a specific enzyme is required to catalyze (speed up) the reaction. These enzymes are required for the reaction to take place, but are not consumed themselves in the reaction.
Why are enzymes placed in laundry detergent?
Enzymes are proteins that speed up chemical reactions. Various materials can make up stains on laundry, and enzymes can help break down protein, lipid, carbohydrate and starch based stains, so it's really versatile. Catalysts are not used up in chemical reactions; therefore, a small amount of enzymes are capable of doing a lot of work. Also, since they're proteins, they're basically safe, non-toxic and bio-degradable.
What protein are vital to live things because they speed up chemical reaction by up to a trillion times?
Enzymes, they are socalled bio-catalysts.
What proteins are vital to living thing because they speed up chemical reaction by up to a trillion time?
Enzymes, they are socalled bio-catalysts.
Chains of chemical reactions in living organisms are called?
Metabolic pathways. These pathways involve a series of interconnected chemical reactions that convert molecules into energy or create necessary building blocks for the organism. Each step is catalyzed by specific enzymes to maintain a balance of energy and essential molecules in the organism.
