All.FunNone Created by: xopriyaCreated on: 14-04-18 16:04 what does the rate of diffusion depend on? distance, concentration & surface area 1 of 13 how does distance affect the rate of diffusion? substances diffuse more quickly when they don't have as far to move 2 of 13 how does concentration affect the rate of diffusion? substances diffuse faster if there's a big difference in concentration between the area they are diffusing from and the area they are diffusing to 3 of 13 how does surface area affect the rate of diffusion? the more surface area there is available for molecules to move across, the faster they can get from one side to another. 4 of 13 what is the job of the lungs? to transfer oxygen to the blood and to remove waste carbon dioxide from it 5 of 13 rate of diffusion? proportional to surface area x concentration difference / thickness of membrane 6 of 13 cardiac output= heart rate x stroke volume 7 of 13 what is respiration? the process of transferring energy from the breakdown of organic compounds. 8 of 13 why is respiration an exothermic reaction? because energy is transferred to the environment 9 of 13 what is anaerobic respiration? without oxygen. it transfers less energy than aerobic respiration so it's much less efficient 10 of 13 what happens in anaerobic respiration? the glucose is only partially broken down, and lactic acid is also produced 11 of 13 word equation for anaerobic respiration in animals glucose --> lactic acid 12 of 13 word equation fr anaerobic respiration in plants glucose --> ethanol + carbon dioxide 13 of 13
