The process by which matter is changed into new substances is called a chemical reaction. During a chemical reaction, atoms are rearranged to form different molecules with new properties compared to the original substances.
A change in which one or more new substances are formed is called a chemical change or chemical reaction. During this process, the original substances undergo a transformation that alters their chemical composition, resulting in the creation of new substances with distinct properties. Examples include combustion, rusting, and digestion. Unlike physical changes, which do not create new substances, chemical changes often involve energy transfer and irreversible processes.
These substances are called catalysts.
True. A chemical change refers to a process where substances transform into new substances through a chemical reaction, involving the breaking and forming of bonds. This transformation alters the chemical properties of the original substances.
The type of digestion where food is digested is called mechanical digestion and chemical digestion. Mechanical digestion involves physically breaking down food into smaller pieces, while chemical digestion involves the breakdown of large molecules into simpler substances with the help of enzymes.
Digestion is the process of breaking down food into simpler substances. Digestion is of two types: mechanical or physical digestion, and chemical digestion.
These substances are called nutrients.
These substances are called nutrients.
These substances are called nutrients.
chemical digestion
Nutrients are substances that are absorbed by the body through the process of digestion.
Nutrients are needed by body cells.
The process by which food is broken down into simpler substances is called digestion. This involves the mechanical and chemical breakdown of food in the digestive system, leading to the absorption of nutrients by the body.
There are many. Digestion is a twofold process; physical digestion and enzymatic digestion. Physical digestion is the act of eating food to break it into smaller parts. Enzymatic digestion is where enzymes (chemical compounds produced by the body) break the food down at a molecular level. Enzymes include salivary amylase, pepsin, lipase, trypsin and many, many more.
Mechanical digestion. The actual grinding and physical breaking down of food. Chemical digestion breaks down food using chemicals/enyzyms and chemical reactions.
These substances are called nutrients.
