hi ms beh. at 30:35 i think u misinterpreted the slide? i think the slide meant that generally there should be no or few proteins in urine as the proteins dont pass through the basement membrane of bowmans capsule and so retained in blood and the ones that do pass through the basement membrane at the bowmans capsule would be reabsorbed back into the blood at pct. but what u said was that long term presence of protein in urine MEANS most proteins molecules dont pass through the basement membrane (but it actually should mean that proteins are now passing through the basement membrane and not being retained in the blood as it should have been). sorry if im missing out on anything tho and really appreciate the free videos

Hi Ms. Beh! I had similar questions for this vid also: 1. What's the control centre? Is it the pancreas, overall? 2. In the book the effectors are liver and muscle cells? In past papers is it alpha and beta cells? In that case there both receptors and effectors? Thanks in advance)
@behlogy

1) Control centre typically refers to the brain. In this case, no control centre per se bcs this pathway doesnt involve the brain. 2) huh never noticed that the book said that! The effectors can be alpha and beta cells, and muscle cells, and liver cells hahah. Again, they all csrry out processes and carry out a response. Just in different ways. If you are unsure, write all three as the answer in exams!

Your video is very useful. It helped me out especially with how the negative feedback mechanisms are involved with regulating blood glucose concentration with reference to insulin in liver and muscle cells as well as to glucagon in liver cells. Overall this video is a great resource for refining my understanding on homeostasis in general.

miss, if we run out of space and just write the summarized version like "inhibits gluconeogenesis" will they still give us a mark? As the statement doesnt explain what the glucose was produced from.

Hello! That's a....tough question. Bcs people tend to just study the "most important" ones only... but in fact, all chaps are important and are interconnected. Also, every chapter comes out for every paper! So don't skip any! But okay... important *concepts* that apply throughout AS and A2 i think would be... - prokaryotic, eukaryotic and viral cell structure - biological molecules, esp proteins - enzymes - transport mechanisms - DNA structure, transcription and translation - mutation - cell division (mitosis and meiosis) These concepts are basics in AS, but tend to appear again and again throughout the syllabus.

Hello Ms. Beh, I just had a question regarding the urine dipstick tests. In your video you said that glucose ----> gluconolactone + hydrogen peroxide in presence of glucose oxidase catalyst. But I think in the textbook and one of the 2022 past papers (May/June 41) they say that glucose ----> gluconic acid + hydrogen peroxide in presence of glucose oxidase catalyst instead. Which one is correct ?

Gluconolactone is a cyclic ester of D-gluconic acid. So i guess it would both work. My formula was based on the textbook

Hi, Mrs.Beh! I'm confused about something. At 28:00 you said the glucose in blood lowers water potential of blood, and one of the things it results in is dilute urine. Isn't low water potential detected by hypothalamus, which causes ADH to be released from posterior pituitary, resulting in higher blood water potential and more concentrated urine?

@@Abd0_25 well the case is a little different here. initially due to high glucose conc in blood the water potential of the blood is low. as a result water moves out of cells into the blood so NOW the blood has more water, thus the resulting final urine formed will be more dilute. i might be wrong tho

in diabetics, why are proteins and fats used for respiration when the glucose isn't entering certain tissues only? like isnt it going to enter all respiring tissue except the liver, muscles and fats
@behlogy

In general, glucose isnt getting absorbed into ALL cells properly, and converted into glycogen. So it stays in the bloodstream and affects osmotic balance (aka water leaves the cells more/ less water is absorbed). so it's not just specific organs
