I think this channel is the only (good) channel with such a variety of topics covered... Seriously, I've watched your videos whilst studying for every exam I have! Thank you so much!
Do you have a microbiology playlist? I got an A in biochemistry thanks to you, it would be great to have something similar for micro. You're amazing btw. :)
No thank you man, you have a way of doing your presentations that really help me understand your subjects. I really appreciate it and really hope you keep the videos coming.
correction (i think): when a cell is placed in a hypertonic solution water moves out of the cell since solute concentration is higher outside while water concentration is higher inside the cell. therefore water moves out of the cell and the cell shrivels
thank you so much for this review - i am currently preparing for medical microbiology and I am watching these as a review. Please post more microbiology videos :D
he means a HYPOtonic solution. If it were HYPERtonic, the water would move outside the cell decreasing the pressure, which contradicts the point! Hypotonic has a higher solution inside, so water would move from low (outside) to high (inside), that would increase the Pressure inside, which the Cell wall resist. I had to recheck my notes and all because that part didn't seem right to me, but good video nonetheless :)
Perfect explanation like usual. Helped me with biochemistry. Now have exam in 2 weeks. And cant study more time is limited. But u are always a help. Thank u
Can you explain the part of the hypertonic solution ? I was sure it means that there are more solutes outside the cell. THANK YOU! and as always your videos are pretty amazing !!
great , but I think there is something wrong , when a cell is placed in hypertonic solution that means there is less solute inside the cell and water will tend to move from inside to outside
Hes referring to the inner environment of the cell. Usually the terms "hyper-" and "hypotonic" are taught referring to the extracellular environment, but they can be used to refer to any environment relative to its surrounding environment.
Very helpful. Is it true that it's the gram negative bacteria that leaves behind the liposaccharides or endotoxins? If so, why is it that gram positive bacteria doesn't? Thanks.
