What else can I help you with?
Any chemical reaction that involves the loss of one or more electrons by an atom or ion is a?
It is an oxidation reaction.
Is photosynthesis a chemical property?
The energy provided by absorbing light can substitute for the heat energy that usually accelerates chemical reactions. More fundamentally, any endothermic chemical reaction can occur because an increase in entropy compensates for any heat absorbed by the reaction to make the free energy change negative.
Which molecule is made during the light-dependent reactions?
Photosystems are the light-harvesting units of the thylakoid membrane.Each photosystem is a complex of proteins and other kinds of moleculea and includes an antenna consisting of a few hundred pigment molecules. When any antenna molecule absorbs a photon, the energy is transmitted from pigment molecule to pigment molecule until it reaches a particular chlorophyll a.Only this chlorophyll molecule is the reaction center and the first light-driven chemical reaction of photosynthesis occures.
What is the molecule that is changed by the enzyme?
The molecule that is changed by an enzyme is called the substrate. Enzymes catalyze chemical reactions by binding to their specific substrate molecules and converting them into products. This process often involves the enzyme facilitating the breaking or forming of chemical bonds within the substrate molecule.
What is an enzyme and why is it important to living things?
Enzymes are any of several complex proteins that are produced by cells and act as catalysts in specific biochemical reactions. They help break down foods you eat and play a role in major chemical reactions. For example, without enzymes we could not break down milk because it contains lactose. People that don't have the enzyme lactase are lactose intolerant. This shows how enzymes are so important to living things.
Name for any substance that speeds up the rate of chemical reaction?
A substance that speeds up a chemical reaction is known as a CATALYST.
The role of catalyst in chemical reaction?
A catalyst speeds up the rate of a chemical reaction.
What chemical speeds up the chemical breakdown of food?
A substance that speeds the changing of food into a usable form* is called an enzyme. More generally, in any chemical context, a substance that speeds a reaction without itself being changed is called a catalyst._______________________________________*This changing of food into a usable form is called "digestion".
What speeds up in chemical reaction?
There are numerous ways to affect the speed of a chemical reaction. They are add a catalyst, increase the concentration of reactants, increase surface area of reactants, increase pressure, and increase the energy in the environment around the reaction.
What is the substance called that increases the rate of reactions in living systems?
A catalyst is any chemical that speeds up a chemical reaction. It does this by lowering the activation energy required for the reaction to take place. A catalyst that occurs in an organism is called an enzyme.
What happens during a reduction/oxidation reaction?
An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron
Why isn't catalyst listed in a reaction?
In any chemical reaction, generally only reactants and products are listed. A catalyst is something that is used during a chemical reaction to change the rate of reaction but does not chemically interact with any of the reactants . It does not change any chemical propertied, it just speeds up the reaction. Since it's not reactant or product, it's not usually listed in a reaction. Catalysts may be indicated in the reaction by beings shown as a superscript over the arrow. This example shows platinum as a catalyst H2C=CH2(g) + H2(g) ----- Pt----> H3CH-CH3(g)
Is there a chemical reaction when a car is dring through rain?
Any chemical reaction.
What is a substance that helps chemical reactions?
A substance that helps chemical reactions is called a catalyst. It speeds up the rate of a reaction by providing an alternative pathway with lower activation energy. Catalysts are not consumed in the reaction and can be used repeatedly.
What is the melting temperature of a molecule?
A molecule is not an unique entity. It is common to any substance. Any no. of atom which combine together by chemical bonds form a molecule. The melting point of any molecule depends upon its chemical composition.
What helps speed a chemical reaction?
Increasing temperature, increasing the concentration of reactants, using a catalyst, and reducing the particle size of reactants can help speed up a chemical reaction by providing more energy for successful collisions between molecules.
How can you change the rate of chemical change in a substance?
This is a very vague question and would depend on the chemical that you are talking about. The easiest way I can think to explain it on a wide variety of chemicals is by using a catalyst (speeds up the process of a chemical reaction), or the use of an antagonist (Slows a chemical reaction). I hope this helps, but without any specific chemicals being named this is the best i can do. :) By heating we can change the rate of chemical change(reaction).
