Early-acting stress sensors provide the initial signal for the stress response,  several possible examples of stress-sensing mechanisms that act early in the pathway have been identified. They include:
A) calcium channel (cyclic nucleotide-gated calcium channel) that senses changes in temperature
B) A kinase (SnRK1, a SNF1-related kinase 1) that senses energy depletion during stress
C) A plasma membrane histidine kinase (ATHK1) that senses osmotic stress
D) A leucine rich repeat receptor kinase (LRRK) protein (Srlk)
E) An endoplasmic reticulum transmembrane sensor inositol-requiring enzyme 1 (IRE1)
And activating several response after sensing these mechanisms;
i) activates hundreds of stress-response transcripts
ii) that functions as an upstream regulator of salinity responses in Arabidopsis
iii) that is required for acclimation to heat stress
iv) that is required for heat tolerance in plants
v) activates ABA-dependent and ABA-independent responses
Which of the following is the correct match the activating response with its sense mechanism;

The glucose uniporter GLUT1 has a Km of 1.5 mM for D-glucose and 30 mM for D-galactose.  At a concentration of 5 mM for each, what is the rate of glucose transport relative to galactose transport?  The Vmax may be assumed to be the same for both.
