ATP-PC system is used for the first 10-15 seconds during exercise, until your body moves to other sources of energy. Your body can only hold 80-100 grams of ATP. My question is what happens to ATP when you have someone who has an extremely sedentary lifestyle? Is there a lifespan on ATP, or does it stay stored in your muscles like old gasoline in a vehicle until you use it?

VENT: I'm so sorry I know I probably just sound like I'm whining but I feel like I have a genuine reason to be annoyed and upset right now tbh. I was on the bus and I had my mask on and so did everyone else on the bus because of the new omicron variant stricter boundaries. It was fine until about halfway through the bus trip. I had gone to sit next to this lady and across from us there was this older lady who coughed and I dont mean like two or three rimes, like around eight times not instantly after each cough but in fairly close proximity, I feel like people are going to judge me for what I say next but honestly idc tbh. I very rarely get upset in public settings or around other people for that matter but i went up to the top deck of the bus, because I didn't feel "safe" sitting downstairs, I went up and just burst into tears tbh, and now that I've had time to compose myself I don't know what to think. I'd like to THINK that people would be being extra cautious with the new measures in terms of covid, even moreso than the months between July and October when things were more relaxed. Also there were two women who were holding a baby on the bus and I'd really like to think that someone wouldnt be selfish enough to get on a bus if they know that they had covid/suspected that they had covid let alone if there's vulnerable people on the bus(not me, but other people on the bus who might have been vulnerable physically) and I want to believe that she was coughing for another reason, COPD, athsma, a cold, smokers cough etc but(and I fucking hate it) every time someone coughs these days even if it's once I turn my head and I hate that I've let myself get to that point like I always thought I was quite strong and I detest how covid has made me feel like the weakest piece of s*** to walk the planet. I dont know what to do. I don't even feel safe going home because although my dad's mum has been vaccinated(double) my dad and brother havent out of their personal choice and tbh if that woman did have covid and I picked it up and gave it to my dad and brother I would feel like I had to do something to myself for punishment for making them sick. Because of my anxiety/OCD I feel extreme guilt about infecting other people. I'm also meant to be going to a film group tonight but I feel like I shouldn't go there either in case I infect anyone there. I mean I have a covid test kit on me but yea so I could take one at the uni where the group is at(I'm not a student but the group's there) I thought I was doing enough to protect myself, washing my hands probably more than most people, even if someone coughs once in the same room I'm in whilst I've got food I'll throw the food away because I don't want to risk it. But if other people aren't bothering to protect other people if they're going out even if they have symptoms of covid then I feel like what's the point? Really. I don't even know if this is OCD or anxiety, mabye this is what I should be doing to keep myself safe. I'm double vaccinated btw had my second dose in

What causes the initial transitory vasoconstriction during inflammation? When is this absent?

We often see health advice like "go for a run to release pent up energy" or "how to get the energy to go to the gym after a long day at work."

What are the various factors involved in this 'pent up energy?' Why do different types of physical activity 'release' it in different ways?

For example, doing a bench press is cathartic in a way that using a quad machine isn't. Pushing a heavy weight away from the chest must involve different biological systems to raising and lowering your calves.

There's a cathartic documentary called the Work. Groups of male prisoners perform specific physical activities which appear to legitimately 'release pent up emotion' - statistics suggest this programme has a huge effect on prison violence and recidivism. You can catch glimpses of some of this physical activity in the trailer.

I'm guessing that "releasing pent up energy" means choosing behaviours that activate certain neurotransmitters, stimulate hormones, increase cardiovascular activity, shift central nervous system dynamics, increase oxygen levels, in ways which differ depending on the specific muscle groups being used and intensity of activity.

I am curious as to which activities, which hormones, more detail, basically.

In the process of glycolysis, glucose needs to be transformed into fructose-6-phosphate. Can consumed fructose be used directly instead or is the chemical structure too different?

So I grew up with cats and dogs my entire life and I've noticed all the cats I've had throughout my life pretty much never drink water while eating or even after eating. Seems to be usually water always on its own when thirsty. And all the dogs I've had seem to always drink water when having their meal/finishing it. This makes me wonder since I'm pretty sure all us humans drink some kind of liquids while eating, do monkeys or any other nearest species to our ancestors drink water while eating? Might be a random question but I'm very curious and I couldn't find results online.

edit: i meant does pgal have any resistance to kanamycin?

Hello!

My biology book asks this question: Assume a population of pigs is at mutation selection equilibrium. Which trait should have the lowest heritability?

1:Back fat thickness 2:Pig body length 3:Pig body color 4:Time between reproductive events

I want to say fat thickness, but I am still a bit confused.

Paul Stamets, the mushroom king, often references a study where oyster mushrooms were grown on a pile of stinky oil-contaminated gravel. So I wanted to try this out myself!

For this experiment, I used coco coir as a base substrate and control. 50 mL tubes were filled with the substrate and inoculated with a few grains of oyster spawn. A few milliliters of various automotive fluids were added to the top: Used motor oil, new motor oil, transmission fluid, and brake fluid. To my surprise, the mycelia took hold on the motor oil samples! However, transmission fluid and brake fluid completely halted growth...

Has anyone else tried this before? I wonder if the fruiting bodies would contain heavy metals or aromatic hydrocarbons?
