Answer in no.2=

"•~~Several types of energy conversion occur in cells. Respiration is the process by which raw fuel energy is converted to a form that can be used for cellular work. Cellular work is a set of processes that includes routine housekeeping as well as special functions such as mitosis. All cells respire and do work.•~~"

In Ribosomes And organelles=

Two types of membranous organelles that specialize in energy conversion are the chloroplasts and mitochondria. Chloroplasts use solar energy to make carbohydrates by using photosynthesis.

Both the mitocondria and chloroplasts convert the energy from one to other.
