Answer #1

Ans: In geophysics, gravity method data collecting in the site gravity values varies with respect to time it is one example.

Correction for instrumental drift is based on repeated readings at a base station at recorded times throughout the day. The meter reading is plotted against time and drift is assumed to be linear between consecutive base readings. The drift correction at time, which is subtracted from the observed value. After drift correction the difference in gravity between an observation point and the base is found by multiplication of the difference in meter reading by the calibration factor of the gravimeter. Knowing this difference in gravity, the absolute gravity at the observation point can be computed from the known value of gravity at the base.

1. Aspartate is metabolized to oxaloacetate, which we know via gluconeogenesis can be used to generate PEP. Assuming the PEP then proceeds to pyruvate and acetyl CoA and enters the citric acid cycle, how much ATP could be generated from the complete oxidation of Aspartate if we assume 1 NADH produces 3 ATP, 1 FADH2 produces 2 ATP, and GTP or ATP are equivalent (1GTP=1ATP).
