Apr 26, 2014·Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells.

Chemical reaction - Wikipedia

A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. Classically, chemical reactions encompass changes that only involve the positions of electrons in the forming and breaking of chemical bonds between atoms, with no change to the nuclei (no change to the elements present), and can often be described by a chemical equation.

Collision Theory: How Chemical Reactions Occur - dummies

An endothermic example of chemical reactions. Suppose that the hypothetical reaction A-B + C→C-A + B is endothermic — a reaction in which heat is absorbed in going from reactants to products — so the reactants are at a lower energy state than the products. The following energy diagram shows this reaction.

How Do Enzymes Catalyze Chemical Reactions?

Mar 31, 2020·Different types of enzymes have different types of reactions they activate, and there are some enzymes that must be in particular environments or operate under certain sets of conditions to work well, if at all. Enzymes may also fail to catalyze chemical reactions if they suffer damage.

What Does a Chemical Scientist Do? (with pictures)

Oct 24, 2020·Such work tends to involve conducting experiments, collecting data, and using the collected data to refine experiments or to form theories about various chemical behaviors. Some laboratory work is aimed at synthesizing substances with various specific chemical properties or at understanding and controlling various important chemical reactions.

Chemical Reactions in the human body - BrainKart

Within the cell, chemical reactions break down substances and the energy released is used to do work. This process is known as catabolism. Building up, or synthesis, is the opposite of decom-position.

How Do Cars Run on Chemical Reactions? | It Still Runs

Cars provide us with a means of traveling long distances at great speeds with very little work. But you can’t get something for nothing. Through a series of chemical reactions, cars turn the liquid fuel into energy to get you from point A to point B.

How C-4 Works | HowStuffWorks

­In the chemical reaction, compounds break down to form various gases. The reactants (the original chemical compounds) have a lot of energy stored up as chemical bonds between different atoms.When the compound molecules break apart, the products (the resulting gases) may use some of this energy to form new bonds, but not all of it. Most of the "leftover" energy takes the form of extreme heat.

Cold Pack Chemistry: Where Does the Heat Go? | Science Project

How Do Instant Ice Packs Work? | eHow

Aug 30, 2017·An instant ice pack is a plastic bag filled with frozen gel that is capable of maintaining extremely low temperatures for an extended period of time. Unlike traditional ice packs, instant ice packs do not need to be stored in a freezer before use and can freeze instantly through a chemical reaction.

How to Balance Chemical Reactions in Equations - dummies

When you write an equation for a chemical reaction, the two sides of the equation should balance — you need the same number of each kind of element on both sides. If you carry out a chemical reaction and carefully sum up the masses of all the reactants, and then compare the sum to the sum of the masses of all the products, you see that they’re the same.

Unlike traditional ice packs, instant ice packs do not need to be stored in a freezer before use and can freeze instantly through a chemical reaction.

- The Chemistry of Emotions

Chemical reactions occur because of synapses. Synapses are parts of the nervous system, and it is through these that neurons are able to transmit messages using neurotransmitters. Emotions are typically measured in physiological responses, such as a pounding heart, sweating, blood rushing to the face, and the release of adrenaline.

Chemistry for Kids: Chemical Reactions

A chemical reaction is a process where a set of substances undergo a chemical change to form a different substance. Where do chemical reactions occur? You may think that chemical reactions only happen in science labs, but they are actually happening all the time in the everyday world.

Chemical reaction - Energy considerations | Britannica

Chemical reaction - Chemical reaction - Energy considerations: Energy plays a key role in chemical processes. According to the modern view of chemical reactions, bonds between atoms in the reactants must be broken, and the atoms or pieces of molecules are reassembled into products by forming new bonds. Energy is absorbed to break bonds, and energy is evolved as bonds are made.
