Enzymes lower the activation energy of a chemical reaction.
What best describes a valence electrons?
Valence electrons are the electrons involved in chemical reactions.
What best describes the study of chemistry?
Chemistry is the science who study matter from the point of view of composition, stucture, chemical properties and chemical reactions, synthesis, etc.
What is the best definition for chemistry?
Subject of chemistry studies are chemical composition, chemical structures, chemical reactions, chemical properties, synthesis of chemicals, etc.
Which best describes a chemical oxidation?
loss of electrons
Which statement best explains how enzymes speed up chemical reactions?
Enzymes lower the activation energy of a chemical reaction.
Best explains how enzymes speed up chemical reactions?
Enzymes speed up the chemical reactions by forcing the reactant molecules into their correct orientation. The enzymes also lower the required energy for collision to produce a reaction.
What best describes a valence electrons?
Valence electrons are the electrons involved in chemical reactions.
What best describes chemical equilibrium a reactions have stopped b reactions continue with no effect on the concentration of reactant and products c reactions stop only when a?

Is it true that lowering the temperature slows down most chemical reactions?
most chemical reactions dealing with enzymes preform best in a certain small temperature range, so increased or decreased temperatures could result in the slowing down of reactions
Why are enzymes needed to control chemical reactions with cells?
enzymes are needed to control chemical reactions within cells because the enzymes acts like catalysts. They basically speed up the reactions within the body, and within the cells, so there fore they help the body maintain its internal environment (homeostasis).-Grade 12 Bio student(exact question came on a handout :P)

Enzymes
Which sentence best describes how water helps living things generate energy?
Chemical reactions within cells take place in the presence of water.
In which organ is biological activity of an enzyme present?
Enzymes are present throughout the entire body. Without these enzymes, simple chemical reactions would take too long to complete. Enzymes are best seen in the digestive system and in the stomach and small intestine. There, enzymes go to work breaking up nutrients such as proteins, carbs, and lipids.
