Is there any correlation between a cell's energy usage and its best performance? Perhaps it will accomplish cell death better with higher energy levels versus sticking around when sickly? Otherwise live and do its job better with fewer compromises due to maximum energy usage?
Multiple Slides samples observations on a Microscope device.
Is it possible to design & construct a Microscope (optical or Electron) which can take multiple slides samples instead of a single sample slide at a time?.
Possible construction of the Sample Slides target is a circular disc holding say 5-10 sample slides.
I.e. Different chambers for samples been observed with the Light or Electrons focussed on all t
Do you feel it will be highly beneficial to have CCTV cameras installed in all Microbiology Labs in the COVID-19 times?
As the COVID vaccines are already developed, the research & development carried further in studying and analysing the COVID-19 variants by the Vaccinologists would be captured in real time on the Video monitors in the Pathology labs.

Summarize the ATP yield during aerobic oxidation of glucose for aerobic bacterium.
I'm not sure how many of each structure are in each process, try to figure out what goes in each box, hopefully I will be able to look at the table and figure out the steps in each cycle. I tried filling out a few boxes although I'm not sure they are completely correct.
Table below is intended as a means of summarizing the ATP yield during the aerobic oxidation

True or false: At the site of membrane fusion between an insulin secretory vesicle and the plasma membrane one would expect to see the aggregation of phosphatidylethanolamine caused by the release of intracellular calcium and the formation of a no bilayer hemifusion intermediate.
Inhibiting the BINDING of Candida Albicans to Monocyte-derived DENDRITIC cells.
This is a totally random question and I am a big noob.
My question is:
If a drug Inhibits the BINDING of Candida Albicans to Monocyte-derived DENDRITIC cells does it mean it protects you against Candida Albicans infections?
There is this medicine that is used to "improve" the immune system. I was reading an article about it, and it said w

Cell Division: Stimulated Microscopic Activity-View of An Onion Root Tip
The actively dividing root cells are located near the tip of a root. A dye is applied to a sample of these cells. The chromosomes, of the cells, accept the dye and appear bright red compared to other cell structures.
For the following questions, identify the correct cells by referencing their location on the chart. Name the ROW letter first, followed by the COLUMN number.
Key points in this Hematopoietic Stem Cell article?
I was pointed to this article to answer some questions. Now I don't expect to have all these questions answered, I just need some guidance on some key points because I am very new to reading these research papers. This is the first paper I've read and I urgently need help. Anything would be great appreciated. Thanks!
Distinguishing lesions of upper and lower motor neurons with specific locations
In a given case where a patient has weakness in a certain area, how would you best guess where a specific location the lesion would be (of an upper motor neuron or lower motor neuron) that would be causing the weakness?
I'm looking for a photo of Saccharomyces cerevisiae(wild type) and Saccharomyces cerevisiae(fab1mutant) at 100X oil immersion, it would be awesome if the pic has a scale bar. Thank you
I have a question regarding calculating how much of a sodium gradient ([Na+]out- [Na+]in) is required to maintain a glucose concentration of the following: inside the cell is 10mM, and outside the concentration is 0.01mM. The temperature is 310K. I used the equation (RT)ln( (s)inside/(s)outside ) + zFVm and got delta g equaling 2.87kcal/mol or 2871.25cal/mole. Is there more I have t

Mutations in which additional genes are found in almost all aggressive metastati
a 45 year old male diagnosed with metastatic adenocarcinoma was determined to have a subset of genes whose over expression was characteristic of a metastatic signature. Up regulated genes in the signature include: SNRPF, HNRPAB, DHPS and securin. Mutations in which additional genes are found in almost all aggressive metastatic human tumors? a.Ras b.Myc c.P53
cystic fibrosis occurs because of a mutation in the gene that codes for an active transport(CFTR) in lung tissue that is responsible for transporting chloride ions from the interior lung surface into the cell. In the mutated protein, chloride ions are not transported across cell membranes, and build up in the extracellular fluid. About 1 in 2000 humans inherit a mutation in the CFTR
Timelines for biofilm development and various cellular processes?
I cannot seem to find good information on how long it takes a bacterial cell to divide. How long it takes to produce and excrete various cellular products? How long does it take for a biofilm to develop? When does it surpass a monolayer?
Which of the following images makes the best argument for recombination?
Alleles of many different genes have been implicated in inheritance of a predisposition to skin cancer. Two are BAP1 located at 3p21and CDKN2a located at 9p21. Consider a man who has two different alleles of BAP1 (call them A and B) and two different alleles of CDKN2a (call them C and D). The man inherited the BAP1A and the CDKN2aD alleles from his mother. From his father
What are the causes of failure to induce Leukemia in recipient mice?
A biotech company discovers a new drug that affects the stability and activity of BCR-ABL. You want to test its effect on Chronic myeloid leukemia cells. You got interesting preliminary results when you treated CML cell lines in vitro and you want to move one step further to test its effect in vivo on the CML mouse model. You read the article entitled "Establi
What is the minimum bactericidal concentration of each antibiotic?
The broth dilution test can be used to determine the effectiveness of an antibiotic. In this test, serial dilutions of the antibiotic were set up in the wells of a microtiter plate. Equal amounts of broth culture of Staph aureus were added to each well. After incubation, the wells were examined for bacterial growth. Wells with no growth were subcultured in nutrient broth without the
The basal lamina of the kidney glomerulus is a thick porous structure that acts as a filter to control the movement os solutes into urine. Ut selectively allows solutes to pass through based on their charge, shape, and size. Positively charged and neutral solutes pass through the basal lamina more easily than negatively charged ones.
I have a cell with a permeable membrane to Na+, K+ and Cl- . The concentration inside is different from the outside (for the 3 ions) and the the electro diffusive flows are in equilibrium simultaneously (Φ=0).
How can I deduce the mathematical condition that satisfy the Donnan equilibrium for those 3 ions?? Can somebody help understand this?
A Mammalian cell (permeable to Na+, K+, Cl-, with the usual distribution of ions) has the following values for ionic equilibrium potentials: ENa=+60 mV, EK = -80 mV and Ec1 = -85 mV. What is the initial direction of movement of each ion (i.e. from outside to inside or vice versa) if the membrane potential is suddenly shifted (this can be done experimentally by i
Gene etoh-1 is induced in yeast cells when treated with high levels of ethanol. A mutation in region 1 located in the upstream cis acting regulatory region of etoh-1 results in high-level RNA transcription, and a mutation in region 2 results in increase in transcription. How are the regions functioning normally in yeast to regulate gene expression? In other words, how are the m
