What accelerates a chemical reaction in a cell?
What accelerates a chemical reaction in a cell?
Enzymes are proteins that have a specific function. They speed up the rate of chemical reactions in a cell or outside a cell. Enzymes act as catalysts; they do not get consumed in the chemical reactions that they accelerate.
What can speed up a chemical reaction?
There are four main factors that can affect the reaction rate of a chemical reaction:
- Reactant concentration. Increasing the concentration of one or more reactants will often increase the rate of reaction.
- Physical state of the reactants and surface area.
- Temperature.
- Presence of a catalyst.
What accelerates a reaction?
Explanation: A catalyst provides an alternative route for the reaction which lowers the activation energy. Thus, the rate of reaction increases.
What are the types of chemical reactions?
The five basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion. Analyzing the reactants and products of a given reaction will allow you to place it into one of these categories. Some reactions will fit into more than one category.
What is not a chemical reaction?
Melting of candle wax on heating is an example of physical change no chemical reaction is taking place only the change of state from solid to liquid state.
Can water be broken down by a chemical change?
A chemical change is a change that produces matter with a different composition. Many compounds can be decomposed into their elements by heating. When sugar is heated, it decomposes to carbon and water. Water is still a compound, but one which cannot be broken down into hydrogen and oxygen by heating.
What type of chemical reaction is souring milk?
1 Answer. That’s a chemical change.
Why soaring of milk is a chemical change?
Souring of milk is a chemical change because during that process acidification takes place and soured milk is produced. This sour milk has different chemical properties from fresh milk. But heating the solution produces a new substance (ferrous sulphide) which has different chemical properties.
