Cellular Metabolism and Energy Production Quiz

To maintain life by providing energy for growth, reproduction, and responding to environmental changes.

Anabolism involves building larger molecules from smaller ones, requiring energy, while catabolism breaks down larger molecules into smaller ones, releasing energy.

ATP is the energy currency of living cells, converting the energy liberated from the oxidation of organic fuels into a usable form for cellular functions.

<p>Biological oxidation is important for the metabolism of amino acids like phenylalanine into tyrosine, which is needed for thyroid and catecholamine hormones synthesis. It is also crucial for the detoxification of drugs, pollutants, and chemical carcinogens.</p> Signup and view all the answers

<p>The two types of cellular respiration are aerobic respiration, which requires oxygen and is more efficient in ATP synthesis, and anaerobic respiration, which does not require oxygen.</p> Signup and view all the answers
