i need a description of one cellular activity that uses ATP. i dont really understand the concept, so i need some help.

also how do autorophs obtain energy, and how do heterotrophs obtain energy?
 
Hey Rachel-

Wikipedia has lots of good information about ATP. Here's what I found briefly but I'll leave the site so you can read the whole article if you need!

ATP transports chemical energy within cells for metabolism. It is an energy source produced during photosynthesis and cellular respiration and consumed by many enzymes and a multitude of cellular processes, including biosynthetic reactions, motility, and cell division.[2] ATP is made from adenosine diphosphate (ADP) or adenosine monophosphate (AMP) and its use in metabolism converts it back into these precursors. ATP is therefore continuously recycled in organisms, with the human body turning over its own weight in ATP each day.[3]

An autotroph [α] is an organism that produces complex organic compounds from simple inorganic molecules using energy from light (by photosynthesis) or inorganic chemical reactions.

Autotrophs are the producers in a food chain, such as plants on land or algae in water. Bacteria which derive energy from oxidizing inorganic compounds (such as hydrogen sulfide, ammonium and ferrous iron) are chemoautotrophs, and include the lithotrophs.


A Heterotroph (Greek ἕτερος heteros = another and τροφή trophe = nutrition) is an organism that uses organic carbon for growth.[1] This contrasts with autotrophs, such as plants, which are able to directly use sources of energy, such as light to produce organic substrates from inorganic carbon dioxide.
