Microscopic examination
The analysis of minute organisms, cellular organization of any biological structure, and composition of body fluids with the help of a microscope is known as microscopic examination. The magnification of specimens or samples under study helps in attaining a clearer picture of it.
Gram Staining
Named after Hans Christian Gram, a Danish bacteriologist, Gram stain is one of the most powerful staining techniques within microbiology. This technique was introduced in 1882 to identify pneumonia-causing organisms. The Gram staining technique uses crystal violet or methylene blue as primary staining colors to distinguish gram-positive from gram-negative organisms. Under a microscope, the gram-positive organisms appear purple-brown, retaining the primary color. Gram-negative organisms appear pink or red as they do not acquire the color of the primary stain.
Question
Transcribed Image Text:The following table shows experimental results of the glucose transport rate, mM/sec, following facilitated diffusion by glucose carrier proteins. (Recall: the starting conc. L
represents glucose added to one side of the membrane; distilled water, omM of glucose was added to the other side of the membrane).
The rate of glucose transport was 0.0031 mm/sec with 8mM of glucose (run number 4, highlighted); the rate decreased to 0.0017 mM/sec with 10mM of glucose (run 5,
highlighted). Why was the rate of glucose transport slower when the concentration gradient was increased?

There was no NaCl- added with 10mM of glucose; sodium is required for transport by the glucose carrier protein
There were fewer carrier proteins used with 10mM of glucose, so they reached saturation and transport slowed
The glucose carrier protein transports against a concentration gradient, so transport will be slower with a larger concentration gradient.
There was not ATP added with 10mM of glucose; ATP is required for transport by the glucose carrier protein
