Transfers of heat
-
Convection
-
convection currents are created because particles heat up, vibrate, expand and become less dense so they rise
-
-
Respiration
aerobic respiration (occurring in the mitochondria of cells) equation is glucose + oxygen = carbon dioxide + water (+ energy released), it is an exothermic reaction, releases some energy as heat, uses oxygen
anaerobic respiration (not using oxygen) in animal cells equation is glucose = lactic acid (+ energy released), it is an exothermic reaction
-
animal cell
cytoplasm, nucleus, cell membrane and mitochondria
-
plant cell
