Describe how enzymes catalyze metabolic reactions by lowering activation energy?
Enzymes lower the activation energy of metabolic reactions by binding to the substrates and stabilizing the transition state. This stabilization facilitates the breaking and forming of chemical bonds, making the reaction more likely to occur. By doing so, enzymes speed up the reaction process without being consumed in the process.
What is enzyem?
Do you mean Enzyme? Enzymes are proteins that participate in cellular metabolic processes with the ability to enhance the rate of reaction between biomolecules. Some enzymes can even reverse a reaction from the direction it would normally take, by reducing the activation energy (Ea) to the extent that the reaction favours the reverse direction. Simlarly, enzymes can catalyze reactions that might not otherwise occur, by lowering the Ea to a more "affordable" level for the cell. Enzymes can be isolated using various protein purification methods. The purity of an enzyme preparation is measured by determining it's specific activity
Do proteins control chemical reactions in a cell?
Yes, proteins called enzymes play a crucial role in controlling and facilitating chemical reactions in a cell. Enzymes act as biological catalysts, speeding up reactions by lowering the activation energy required for the reaction to occur. They have specific binding sites where they interact with specific molecules, allowing them to regulate the rate and specificity of reactions in the cell.
Which system is responsible for producing enzymes?
The endocrine system is responsible for producing enzymes. Hormones released by the endocrine glands stimulate the production of enzymes in various tissues and organs of the body. Enzymes play a crucial role in facilitating chemical reactions within the body, and their production is regulated by the endocrine system.
What do catalysts and enzymes have in common?
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.
What is the purpose of using HCl reagent in chemical reactions?
Hydrochloric acid (HCl) is used in chemical reactions to provide a source of chloride ions, to adjust the pH of the reaction mixture, and to catalyze certain reactions.

What is the difference between lyase and ligase enzymes in terms of their functions and mechanisms of action?
Lyase enzymes catalyze the breaking of chemical bonds in molecules without using water, while ligase enzymes catalyze the formation of new bonds between molecules using energy from ATP. Lyase enzymes work by eliminating groups from substrates, while ligase enzymes work by joining two molecules together.
Without enzymes chemical reactions necessary for life would not occur at a rate sufficient to sustain life True or False?
Usually, to have a fast chemical reaction, you want high temperatures. However, it is not favorable to have these high temperatures in cells (for many reasons; ask another question if you want reasons) Therefore, organisms use enzymes to catalyze reactions. Essentially, you're achieving the same goal of a fast reaction by using a different mechanism (enzyme vs. high temp). In sustaining life, you need fast reactions because most reactions occur very very slowly.. The answer to your question is yes..without enzymes chemical reactions necessary for life would not occur at a rate sufficient to sustain life.

The total of all chemical reactions in an organism?
Metabolism is the total of all chemical reactions that occur within an organism, including processes like energy production, growth, repair, and waste elimination. These reactions are regulated by enzymes and can be categorized into two main types: catabolic reactions that break down molecules to release energy, and anabolic reactions that build molecules using energy.
Do enzymes receive help from cofactors?
Yes, enzymes often require the assistance of cofactors to function properly. Cofactors are non-protein molecules that bind to enzymes and help catalyze chemical reactions by assisting with substrate binding, stabilizing transition states, or acting as electron carriers. Some examples of cofactors include metal ions, coenzymes like vitamins, and prosthetic groups.
How does wash powder work?
Biological washing powders work by using enzymes, which are biological catalysts*, to 'eat' away at the bacteria in clothes. *catalysts - A chemical that speeds up chemical reactions. Eg. Enzymes in saliva speed up the chemcal reaction of braking food down to glucose.

By using enzymes scientists can remove and substitute sections of 'quarks' or 'DNA'?
Quarks are fundamental particles of the universe and cannot be subdivided (according to current knowledge). Enzymes are proteins that catalyze reactions and there are no reactions that can 'remove sections' of quarks, which are basically indivisible. If you know about restriction endonucleases and DNA ligases, you'll know that these enzymes can cut and ligate together different pieces of DNA.
