In living cells what is the energy carrier that fuels most kinds of cellular work

Adenosine triphosphate.

There are three basic forms of asexual reproduction, a term which means that offspring can come from one single parent. These three forms are budding, fission, and fragmentation. Fission is when one cell is stretched, pinched in the middle, and then separated into two separate cells. Fragmentation is when an organism is divided into sections and each section regrows, such as some type of worms. Budding means the offspring arises as an outgrowth of the parent cell, such as corals for example. Some types of yeast can reproduce by budding.
