Catabolism

The video tutorial explains a key metabolic process involving the breakdown of large molecules into smaller ones, releasing energy. It highlights how these smaller molecules can be further broken down in cells to release additional energy. The tutorial also covers the catabolism of complex molecules like starch into simpler sugars, known as monosaccharides, which are more easily processed by cells.

What is one of the major processes in metabolism?

• Synthesis of proteins

• Breakdown of large molecules

• Formation of DNA

• Transport of oxygen

What happens to smaller molecules in cells?

• They are converted into proteins

• They are broken down to release more energy

• They are expelled from the cell

• They are stored for later use

What is an example of a large complex molecule that is catabolized?

• Lipid

• Nucleic acid

• Starch

• Protein

What are the simple sugars produced from the catabolism of starch called?

• Oligosaccharides

• Monosaccharides

• Disaccharides

• Polysaccharides

Why are monosaccharides more easily processed in cells?

• They are simpler and smaller

• They require more energy to break down

• They are larger molecules

• They are more complex
