If a reaction results in a negative delta G (free energy), is that reaction spontaneous, or non-spontaneous?
Spontaneous. Free energy measures spontaneity and can be determined from the values of delta H (thermal energy) and delta S (order of a system).
Which metabolic pathway turns glucose into pyruvate?
Which type of diffusion across a cell membrane does NOT require energy or assistance from membrane proteins?
Passive diffusion. Passive diffusion is the movement of ions or particles across a cell membrane down their current gradient. Therefore, a water molecule may passively diffuse across a cell membrane in the direction where its current concentration is lower.
