Answer:
The liver cell with ∆G'° = -2.34 kJ/mol
Note: The question is incomplete. The complete question is given below:
The following data represents cellular concentrations of ATP, ADP, and inorganic phosphate from various mammalian organs. Calculate the actual Gibbs free energy change for hydrolysis of ATP under physiological conditions (assume 37°C). Assume ATP hydrolysis has a standard free energy change of -30.5 kJ/mol. Which cell type yields the greatest free energy change for ATP hydrolysis? Show your work. ATP (MM) ADP (mm) Pi. (mm) Liver 3.5 1.8 5.0 Muscle 8.0 0.9 8.0 Brain 2.6 0.7 2.7 mM=millimolar, ATP=adenosine triphosphate, ADP-adenosine diphosphate, Pi=inorganic phosphate
Explanation:
The equation for ATP hydrolysis is as follows: ATP ---> ADP + Pi
Standard free energy change, ∆G'° = -RTlnK'eq;
where K'eq is equilibrium constant; R = 8.315 J/mol.K; T = 298 K
K'eq = {[ADP][Pi]}/[ATP]
For Liver:
∆G'° = -(8.315)(298) × ln (1.8 × 5.0/3.5)
∆G'° = -2.34 kJ/mol
For Muscle
∆G'° = -(8.315)(298) × ln (0.9 × 8.0/8.0)
∆G'° = 0.261 kJ/mol
For Brain
∆G'° = -(8.315)(298) × ln (0.7 × 2.7/2.6)
∆G'° = 0.79 kJ/mol
The right answers are 5 and 6.
The somatic nervous system is part of the peripheral nervous system <u>(part of the nervous system consisting of nerves and ganglia, and whose essential role is the transmission of information between the central nervous system - brain and spinal cord - and organs)</u>. It intervenes in the voluntary control of movements (or involuntary movements in case of reflexes, but this is different from the involuntary activities) (efferent fibers) and in the perception of external stimuli (afferent fibers).
The somatic nervous system controls the movements of skeletal muscle (which are generally voluntary) and the environmental perception, (think to the arc reflex).
The involuntary activities (proposition 1) mean automatisms like the heartbeat, respiration, secretions of hormones or sweat...
Answer: The correct answer is the last option.
Explanation:
Carrier identification test is a screening test that tells if a person is carrier of a particular autosomal recessive disease. It helps in determining the possibility of passing that disease to a child.
Genetic counsellor is professional who is expert in human genetics, research, lab work, counselling, et cetera. After the test, it is best to contact a genetic counsellor as he can explain the family pedigree of the disease. He can best explain the probability of passing a genetic disease to the child.
