Worked Solution & Example Answer:13. (i) Explain the term metabolism - Leaving Cert Biology - Question 13 - 2016
Step 1
Explain the term metabolism.
Answer
Metabolism refers to all the chemical reactions that occur within an organism, either in a cell or throughout the body. These reactions are crucial as they involve the conversion of food into energy, the synthesis of necessary biomolecules, and the breakdown of waste products.
Step 2
State whether each of the following processes is an example of anabolism or catabolism. 1. Respiration.
Answer
Respiration is an example of catabolism. In this process, organic molecules (typically glucose) are broken down to release energy, which is utilized for various cellular functions.
Step 3
State whether each of the following processes is an example of anabolism or catabolism. 2. Photosynthesis.
Answer
Photosynthesis is an example of anabolism. During this process, plants convert carbon dioxide and water into glucose and oxygen using sunlight, which involves the synthesis of complex molecules from simpler ones.
