After several hours of 'work', the neuro-transmitters are depleted of what they need for good cognitive function. What they need is quality food which most of us don't eat enough of. Synapses are slower to exchange neurons. Basically, lack of active neurotransmitters is the reason for most people who are otherwise healthy. It's not the same mechanism as ...

There is a difference between animals in their requirements for amino acids. For example, cats need high amounts of taurine (and can't make it) and when fed diets lacking enough can go blind. This is why vegans trying to feed vegan diets to their pets can be very bad for the pet. Animal proteins have sufficient taurine for the cat. However, the meat of a ...

The feeling of cold from mints is caused by menthol. Menthol affects the TRPM8 receptor on skin and also in the mouth. TRPM8 is also a general cold receptor: so if you are in contact with menthol the receptor reacts just like when you are exposed to cold (Bautista et al., 2007). The receptor is strongly activated at temperatures below 26 degrees Celsius (...

ATP is the end result of breaking apart glycogen. This isn't a trick question imo, it's in every textbook that glycogen is a primary store of "will soon become ATP" materials, like glucose. The keyword here is "primary," as there are other ways of getting and storing ATP... that is, putting oxygen and glucose into the cells, and then there is always ...

If you are only given glycogen and ATP as choices, then glycogen is the correct answer. The reason for this is, that muscle cells need ATP also for other very important processes (such as keeping the membrane potential stable and preventing cramps). Thus, while ATP is the actual fuel that powers myosin to create the muscle force, the cell needs to keep the ...

This is a typical MCQ which in order to answer you have to have been at somebody’s lectures or be able to read his mind. The antithesis of education! Cells don’t store energy like car batteries. Glycogen in muscle is a store of carbohydrate. It can be used to generate ATP if it is broken down to glucose and the glucose glycolysed. I wouldn’t have chosen ...

The notion that tea and coffee are diuretic and don't count in your daily waterbalance, is an urban myth. At most, both are mildly diuretic (if any). The assumption is based from an old study from 1928 with only three participants. While the small number of participants alone is a good reason to reject the study (it would never get published today) because ...

I am not sure if I can answer the question of why the primary oocyte gets arrested during meiosis (and finishes after fertilization), but the stage of growth the egg is arrested at does vary widely between species; it's not always primary oocyte. This might suggest that the reason is species-dependent. In sea urchins, it's the fully mature ovum that gets ...
