Carefully read the paragraph below discussing the 4 steps of cellular respiration. Provide the missing terms by selecting from the drop down menu provided.  Cellular respiration takes place in 4 controlled steps.  The first step known as [answer1] takes place in the [answer2], and requires the input of [answer3] which will be split in half creating 2 [answer4] and [answer5]. Step 2 known as the [answer6] and step 3 known as the [answer7] will both take place in the [answer8]. Both of these steps create and release [answer9] and some energy molecules. The fourth and final step known as the [answer10] takes place on the [answer11]. During this final step a series of electron carriers will pass electrons down a chain resulting in the production of [answer12].  At the end of the chain oxygen being the final electron acceptor will combine with hydrogen ions to form [answer13]. At the end of cellular respiration a total of [answer14] will have been made from one molecule of glucose. That’s a lot of usable energy!
