Connections Between Cellular Respiration And Other Pathways

So far, we’ve spent a lot of time describing the pathways used to break down glucose. When you sit down for lunch, you might have a turkey sandwich, a veggie burger, or a salad, but you’re probably not going to dig in to a bowl of pure glucose. How, then, are the other components of food – such as proteins, lipids, and non-glucose carbohydrates – broken down to generate ATP? As it turns out, the cellular respiration pathways we’ve already seen are central to the extraction of energy from all these different molecules. Amino acids, lipids, and other carbohydrates can be converted to various intermediates of glycolysis and the citric acid cycle, allowing them to slip into the cellular respiration pathway through a multitude of side doors. Once these molecules enter the pathway, it makes no difference where they came from: they’ll simply go through the remaining steps, yielding NADH, FADH​, and ATP. Simplified image of cellular respiration pathways, showing the different stages at which various types of molecules can enter. Glycolysis: Sugars, glycerol from fats, and some types of amino acids can enter cellular respiration during glycolysis. Pyruvate oxidation: Some type Continue reading >>

  1. KinkingPump

    Hi
    A few weeks ago I was admitted to A&E- long story short my sugar was up around 35 as my pump had kinked, I was vomiting up everything. The sugar had been rising for about 12 hours, the first ketone reading I did practically turned the dip stick black, but within 4 hours it was coming back as no ketones (I know how to down water!) and my BS 7.
    I had an easy day the following day and just slept, drank loads of water and then started trying to do "normal" routine stuff the day after that. It took about a week before I was back to normal, I felt crampy and achey, couldn't concetrate on anything and just wanted to sleep! Is there any way of speeding this recovery up? How long does "recovery" take from an episode like this until you feel normal in yourself again? And how do people manage with work- I was getting tellings off for my lack of concentration, I didn't want to go on the sick per se as I didn't feel that I needed to be home in bed, but equally I wasn't capable of performing (I'm an engineer- not a physical labourer, someone who does calculations and lots of sums!)... What should I have done?
    Thanks for any responses, experiences and tips would be really appreciated- I've been diabetic since I was 9 (now 22) and this is the first time I've had real problems (was a teenager with HBAs in the teens on injections, and only been on a pump 9 months with a HBA of 8 now so guessing I'm a lot more sensitive to the highs that I was before!)

    I kinked mine last night. Was awoken by the pump's blocked-cannula alarm (Aviva Combo), thankfully & nothing untoward had happened.

    I had DKA just before I went on my pump, which was caused initially by a sickness bug. i was on placement for my university degree at the time. I was in hospital for about 24 hours, and then my mum took me home. I had 3 days off to recover, and like you said mainly just slept and drank water. The week following I felt very crampy and achey, and i think it took a week or so to feel "normal" again. Now if my pump ever messes up (on friday night it disconnected over night) and i ended up with ketones, i recovered without need of A&E but I felt rubbish yesterday (tired, crampy, irritable) and today I'm not feeling 100%. I think once youve had a high level of ketones it takes awhile for your body to recover, they are "poisonous toxins" afterall. Hope you feel better soon
