<u><em>-Describe the structure of an ATP module.
</em></u>
ATP plays an important role in releasing and storing energy in cells. It is an ideal source of energy because ATP easily releases and stores energy by breaking and re-forming the bonds between its phosphate groups. The ATP module is composed of three components. These phosphates are the key to the activity of ATP.
<u>Answer:</u>
<em>Movement will be brought about in touch me not plants by the action of various chemicals present at the base of the leaf stalk.
</em>
<u>Explanation:</u>
<em>The leaves of touch me not plant stay upright due to turgor pressure. </em>It is exerted by the water present within its cells. This pressure applies force against the cell wall enabling the plant to remain stiff.
When there is an external disturbance , parts of the plant releases certain chemicals including potassium ions that causes water to diffuse out of cells. <em>This releases the turgor pressure and causes the leaves to shrink. </em>
