in principle, at least, one way to increase the concentration of glucose 6‑phosphate (g6p) is to drive the equilibrium reaction to the right by increasing the intracellular concentrations of glucose and pi. the maximum solubility of glucose is less than 1 m, and the normal physiological concentration of g6p is 250????m. assume a fixed concentration of pi at 4.8 mm. the calculated value of K′eq is 4.74×10−3 m−1. calculate the intracellular concentration of glucose when the equilibrium concentration of glucose 6‑phosphate is 250????m, the normal physiological concentration.
Answers for both scenarios: The concentration (Gle= 13.7 M) can't be soluble in the first scenario while during the second situation the concentration (Gle= 116 μM) is normal and physiologically reasonable.
For the first scenario:
The equilibrium reaction is:
3.8* 10⁻³ = [250*10⁻⁶]/[0.0048][Gle]
Gle = 13.7 M
This can't be soluble at the concentration.
For the second scenario:
c. ΔG⁰ = 13.8 + (-30.5) = -16.7 KJ/mol
-16,700 = -8.315 (298) In Keq
K = 845
845 = [[250*10⁻³] [1.32*10⁻⁶]/ [3.38*10⁻⁶] [Gle]

question content area top part 1 what type of pathogen is described as a plantlike microorganism that typically will not cause infection in a person with a normally functioning immune system?
Fungi is described as a plantlike microorganism that typically will NOT cause infection in a person with a normally functioning immune system.
Bacteria already abound in your body. However, these microorganisms only pose a threat if your immune system is weakened or if they manage to enter a normally sterile area of your body.
Pathogens may spread disease once they enter the body, unlike other organisms.
A pathogen doesn't even need a host to develop and thrive. The infection enters the body of the host, evades the immune system's defenses, and multiplies by using the host's resources before leaving and infecting a new victim. Pathogens can be spread through a variety of techniques depending on the type. Skin-to-skin contact, bodily fluids, airborne particles, feces, and surfaces that have been contacted by an infected person are all ways that they might spread.
Fungi come in numerous types on Earth. There are only roughly 300 reliable sources that are known to be harmful. Fungi can be found almost wherever in the environment, including indoors, outdoors, and on human skin. They spread illness when they grow too much.
