Cells contain parts known as organelles. These parts are specialized. What does this mean?
navik [9.2K]
"Specialized" organelles or parts means that these parts have been modified to carry out a specific function that is unique to them. Organelles are literally "little organs" and each of them in the cell has a specific and distinct function. For example the nucleus is an organelle. It is arguably the most important organelle in the cell. Its specific overall function is that it acts as the cell control center, directing the activities of all the other organelles .i.e. what they need do and when to do it. The nucleus also contains all of the cell's genetic material (DNA).

Catabolism happens as you are breaking down food. For instance, a piece of bread is broken down into simple components your body may absorb, such glucose, through this process (blood sugar).

<h3>What is difference between catabolism and anabolism?</h3>

The series of metabolic processes known as catabolism reduces molecules into smaller pieces that are then either oxidized to produce energy or utilised in other anabolic processes. The process of anabolism produces the molecules the body needs to function. Energy is released during the catabolism process. Energy is needed for anabolic processes.
