Some bacteria get their energy from reduction of CO2 to CH4 by H2. 1. How many electrons are required to reduce CO2 to CH4? 2. Calculate the G for formation of methane based on the two standard reduction potential of -0.171V for reduction of CO2 to CH4 and -0.414V for reductio...
The extracellular concentrations of Na+ and K+ are 135mM and 6mM, respectively. The intracellular concentrations of Na+ and K+ are 10mM and 105mM, respectively. The membrane potential is 75mV. For Na+/K+ ATPase, 3Na+ are exported and 2K+ are imported. Calculate the total free ...
Using your knowledge of trigonometric identities, ﬁnd the exact value of sin(x+y) knowing that x and y are between 0 and π2, that sin(x)=725 and that sec(y)=1312. Your answer must be a rational number, written in the form of an irreducible fraction p/q (such as 2/3...
