As the electrons from these carriers move down the ETC, energy is released. This energy pumps H+ ions across the membrane, creating a proton gradient.\n\nDuring chemiosmosis, the proton gradient created by the ETC is used as an energy source. As the H+ ions flow down the gradient, they pass through ATP synthase, which in turn creates ATP.", "images": {}, "replace": false, "widgets": {}}, {"content": "The correct answers are\n\n[[☃ categorizer 3]]\n", "images": {}, "replace": false, "widgets": {"categorizer 3": {"alignment": "default", "graded": true, "options": {"categories": ["ETC", "Chemiosmosis"], "items": ["Oxidizes NADH to NAD+", "Creates a proton gradient", "Makes ATP using a proton gradient", "Oxidizes FADH2 to FAD"], "linterContext": {"contentType": "", "highlightLint": false, "paths": [], "stack": []}, "randomizeItems": false, "static": false, "values": [0, 0, 1, 0]}, "static": true, "type": "categorizer", "version": {"major": 0, "minor": 0}}}}], "itemDataVersion": {"major": 0, "minor": 1}, "question": {"content": "**Classify each statement as a property of the electron transport chain (ETC) or chemiosmosis.**\n\n[[☃ categorizer 1]]", "images": {}, "widgets": {"categorizer 1": {"alignment": "default", "graded": true, "options": {"categories": ["ETC", "Chemiosmosis"], "items": ["Oxidizes NADH to NAD+", "Creates a proton gradient", "Makes ATP using a proton gradient", "Oxidizes FADH2 to FAD"], "randomizeItems": false, "static": false, "values": [0, 0, 1, 0]}, "static": false, "type": "categorizer", "version": {"major": 0, "minor": 0}}}}}
