Sir, the term “literacy” means something different in each discipline taught in schools. Scientific literacy does not just mean “being able to read, write, and communicate”; it means “being able to read, write, and communicate–like a scientist”. Sarah took a big step by posting this comment. The attention she has paid to what you wrote is evidence that she is in the process of constructing meaning about the subject matter. As her scientific literacy improves, her learning improves—the two feed off of one another.
I must ask, if you meant something different (it’s not coming from thin air), then why did you write it the way you did? In my opinion, you owe her more than a flippant reply.
Cool dog by the way.
Respectfully (and proud as hell of my student), Geoff
Now this brings us to the next part - how do we go from glucose to ATP? This is achieved through the process of "oxidation" - and this is carried out through a series of metabolic pathways. Complex chemical transformations in the cell occur in a series of separate reactions to form each pathway, and each reaction is catalyzed by a specific enzyme. Interestingly, metabolic pathways are similar in all organisms, from bacteria to humans. In eukaryotes (plants and animals) many of the metabolic pathways are compartmentalized, with certain reactions occurring in specific organelles. Basically, cells trap free energy released from the breakdown (metabolism) of glucose. This energy gets trapped in the ATP as it converts from ADP to ATP by the addition of phosphate.
ATP can be formed during CELLULAR RESPIRATION , either in the general cytoplasm during GLYCOLYSIS or in the MITOCHONDRIA via the KREBS CYCLE and the ELECTRON TRANSPORT SYSTEM if oxygen is present. ATP is also formed during photosynthesis in the CHLOROPLASTS of green plants, again using an electron transport system. ATP molecules act therefore as short-term ‘biological batteries’, retaining energy until required for such processes as active transport, synthesis of new materials, nerve transmission, and muscle contraction. An active cell requires more than two million molecules of ATP per second to drive its biochemical machinery.
