If we were to sum the concentration of each intermediate in the tca cycle, we could find the total concentration of carbon backbones in the tca cycle. some metabolic pathways lower the concentration of carbon backbones in the tca cycle since these reactions consume molecules like α-ketoglutarate and oxaloacetate, which are intermediates in the tca cycle. other metabolic pathways increase the concentration of tca cycle carbon backbones, since tca cycle intermediates are end products of those pathways. for each of the following reactions, would the concentration of carbon backbones in the tca cycle increase, decrease, or remain the same? label each reaction with its effect on the overall concentration of tca cycle intermediates.

Density because it’s holyyy

For cyclohexane compounds drawn in a chair conformation:   -axial bonds are vertical  -equatorial bonds are parallel to two bonds within the ring.  thus, as i assume the chair conformation is drawn:   -the x group is in an axial position, as are the five other vertical bonds.  -three axial bonds are on the top face of the ring  -the other three axial bonds are on the bottom face  the position of the second substituent on each ring carbon is equatorial.  gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other.  drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1.  click this link and watch some academic videos that may you more understand the topic 

The answer is the first option just took the test
