Describe how enzymes catalyze metabolic reactions by lowering activation energy?
Enzymes lower activation energy because they have energy. Enzymes help to speed up reactions or start reactions by using their own internal energy to do so.
Do proteins control chemical reactions in a cell?
Yes the protein from your blood stream runs to the lungs leaving them to cause a chemical reaction. You can create chemical reactions in your body using coke and mentos
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.
Are starches with a relatively large amount of amylose digested more quickly than those with amylopectin?
Enzymes are often substrate-specific, meaning they will only catalyze a reaction with a certain molecule. The difference in structure between amylose and amylopectin causes amylase to catalyze one and not the other.
A shorter easier way to show chemical reactions using symbols instead of works is called?

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.
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.
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.

What is the difference between chemical synthesis and breakdown reactions?
Chemical Digestion is where your stomach dissolves the food in your mouth by saliva, or when the enzymes and bile break it down in the stomach.Mechanical Digestion is when you chew the food using your teeth, and when your esophagus swallows the food using peristalsis.

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
What are the advantage to living organisms using enymes to catalyze their reaction?
The most important reason is to accelerate the metabolic reaction of large compounds into small units in order to be assimilated. Although enzymes are subject to the same laws of nature that govern the behavior of other substances, they differ from ordinary chemical catalysts in several important respects:Higher reaction rates. The rates of enzymatically catalyzed reactions are typically factors of 1,000,000 to 1,000,000,000,000 greater than those of corresponding uncatalyzed reactions and are at least several order of magnitude greater than those corresponding chemically catalyzed reactions.Milder reaction conditions. Enzymatically catalyzed reactions occur under relatively mild conditions: temperatures below 100oC, atmospheric pressure, and nearly neutral pHs. In contrast, efficient chemical catalysis often requires elevated temperatures and pressures as well as extremes of pH.Greater reaction specificity. Enzymes have a vastly greater degree of specificity with respect to the identities of both their substances (reactants) and their products than do chemical catalysts; that is, enzymatic reactions rarely have side products.Capacity of regulation. The catalytic activities of many enzymes vary in response to the concentrations of substances other than their substrates. The mechanisms of these regulatory processes include allosteric control, covalent modification of enzymes, and variation of the amounts of enzymes synthesized.
What do catalysts and enzymes have in common?
No, but they go hand in hand. In biology, the catalyst and enzyme join together in the way a key and lock do. The enzyme is either connected to another enzyme when they join, or it is broken into two. The enzyme is portrayed as the key, and the catalyst would be the lock. Each catalyst has a specific enzyme that fits into it, and vice versa.
