The true statements are:
1) Catabolism is the process in which complex substances are broken down, yielding a net output of energy.
Catabolism reactions break down macromolecules (lipids, proteins, nucleic acids and sugar) into smaller units that can be used for further reactions, for energy, for the synthesis of new polymer molecules or be simple waste products.
2) Metabolism is an integrated system in which many of the same reactions participate in degradative (catabolic) and biosynthetic (anabolic) pathways.
Metabolism combine all chemical reactions of an organism. Functions of metabolism include: providing energy form food molecules, synthesis of building blocks of the cell, elimination of the waste products.
3) Anabolism involves the synthesis of polymeric biomolecules and complex lipids from monomers such as fatty acids and nucleotides.
Anabolic reactions are opposite of those in catabolism: these reactions require energy (endergonic processes) for the synthesis of necessary molecules for the cells. That energy is the product of catabolic reactions.
Answer:
Either the Chloroplasts or the cell wall
Explanation:
Answer:
<u><em>The correct option is D) His results gave the first evidence that atoms were made up of smaller particles.</em></u>
Explanation:
Before the experiments performed by Thomson,scientists believed that atoms were the smallest particles with no sub units. The experiments performed by Thomson provided evidence that atom is made up of even smaller particles. The cathode ray experiment performed by Thomson led to the discovery of electrons which are the negatively charged particles of an atom. The protons are the positively charged particles of an atom. Whereas, the neutrons have no charge.
