The first step of gluconeogenesis involves the carboxylation of pyruvate and has a large negative delta G (i.e. very exergonic). Explain how it is possible that this step can be exergonic if we know that adding $CO_2$ onto molecules is fundamentally a destabilizing phenomenon?
The opening weekend earnings for the top 1799 movies of all time have a distribution that is strongly right-skewed, with a mean of $26.2 million and a standard deviation of $22.9 million. 1. Describe the shape of the sampling distribution of 𝑥̅ = the mean opening weekend earnings for SRSs of size n = 10 from this population of movies. Justify your answer. 2. Describe the shape of the sampling distribution
2. Force Vectors Note: All the figures are not drawn to scale unless mentioned otherwise. Problem 2.1: For the system shown in Fig. 1: a) Calculate the magnitude of the resultant force and its direction measured clockwise from the positive u axis. b) Resolve the force $F_1$ into components along the $u$ and $v$ axes and determine the magnitude of the components. c) Resolve the force $F_2$ into components along the $u$ and $v$ axes and determine the magnitude of the components.

FM 2 A photon (a single massless unit of light) encounters a free electron. As we will see later in the course, photons are completely absorbed by atoms all the time, but it turns out that total absorption cannot happen with a free electron. a. Use energy and momentum conservation to show that this is true. Description of Solution: \begin{itemize} \item Draw a before-after absorption picture in the rest frame of the electron. \item Write down the total relativistic energy and momentum of the system before and after. \item Do the algebra to show that both energy and momentum can't be conserved at the same time. \end{itemize} b. Use conservation of 4-vector momentum to show that this is true. Description of Solution: \begin{itemize} \item Draw a before-after collision picture in the rest frame of the electron. \item Write down momentum 4-vector components of both the photon and the electron in the rest frame of the electron before and after the photon is absorbed. \item Show that the sum of 4-vector momenta before cannot equal sum of 4-vector momenta after. \end{itemize}
