PowerPoint presentation for** A-level Biology** (prepared for** OCR Biology A** specification [from 2015] but probably applicable to other boards as well), detailing the stages of aerobic respiration, including an animated explanation of oxidative phosphorylation, and anaerobic respiration with a comparison between animal and yeast cells.
Presentation includes: glycolysis, Link reaction, Krebs cycle with info about why there are 2 cycles per glucose molecule, an animated sequence though the stages of oxidative phosphorylation which demonstrates the role of reduced NAD, the transfer of electrons along the ETC, pumping of H ions, chemiosmosis and phosphorylation of ADP, the role of oxygen and formation of water, and why reduced FAD gives a lower yield of ATP than reduced NAD. Anaerobic respiration starts by revisiting glycolysis and explaining the need for recycling NAD, then compares the processes used by animal cells and yeasts.
The animation is stepped so you can go through it at your own pace, adding further explanation at any stage, and rewind using the back arrow key.
It was prepared using Office 365, so it is possible that some features may not be supported by earlier versions of PowerPoint.
Something went wrong, please try again later.
Concise or although perhaps too concise for teaching and better for revision purposes.
Loved the animation showing Hydrogen ions moving across the membrane during the ETC.<br /> <br /> The whole PPT is very logical for a difficult topic
