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.
Why is the sum of all chemical reaction in the human body known as metabolism?
The sum of the chemical processes in the human body, or in any living body for that matter, is called "metabolism".
What is photolysis and mention its importance in photosynthesis?
Photolysis is any reaction where a chemical compound splited by photon (units of light). In a lay man's language splitting up a chemical compound in presence of light. In photosynthesis photons split water molecule into its constituents and release energy in the form of electrons which are transported to the electron transport chain along electopotential gradient The reaction is a s follows H2A + 2 photons (light) 2e- + 2H+ + A A can be oxygen or in purple sulfur or cyanobacteria can be S
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 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 helps speed a chemical reaction?
A catalyst is a substance that speeds up a chemical process without actually changing the products of 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 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)
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 any chemical substance formed as the result of a chemical reaction?
A reaction product.
Is there a chemical reaction when a car is dring through rain?
Any chemical reaction.
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.
