Respiration stage 1

How Cells Harvest Chemical Energy Cellular Respiration

O 2 CO 2 BREATHING Lungs CO 2 O 2 Bloodstream Muscle cells carrying out CELLULAR RESPIRATION Sugar + O 2  ATP + CO 2 + H 2 O Breathing and Cell Respiration are related Muscles get oxygen from breathing and sugar from food to produce energy during cellular respiration.

Burning glucose in an experiment Energy released from glucose (as heat and light) 100% Energy released from glucose banked in ATP “ Burning” glucose in cellular respiration About 40% Gasoline energy converted to movement Burning gasoline in an auto engine 25% How efficient is cell respiration? energy released from glucose as heat and light = 100% if you burn glucose energy released from glucose stored in ATP = 40% burned during cellular respiration gas energy converted to movement 25% if burned in an auto engine
