Question

Cellular communication and division

In one paragraph connect the following: Mitochondria and Anaphase.

Hints

1. what is going on in anaphase
2. what is required to have that happen
3. how does mitochondria provide anaphase with energy

Answer 1

Anaphase is the third stage of mitosis. It is characterised by the separation of sister chromatids from each other and their movements towards the opposite poles of the cell. The sister chromatids are are attached to the spindle apparatus with the help of spindle fibres. The shortening of spindle fibres lead to the movement of sister chromatid towards the pole. All of this process, separation of sister chromatids and movement towards the opposite pole require energy in the form of ATP molecules. This energy is provided by mitochondria.

Mitochondria undergoes cellular respiration in which it breakdown glucose molecules to release carbon dioxide and water along with the generation of ATP molecules. These ATP molecules are used during anaphase to carry out the processes. Not only in anaphase, but all other cellular activities which are energy dependent use ATP generated in mitochondria during cellular respiration.
