Lecture 7 – Photosynthesis – 9-26-07 Suppose we introduced pores into the inner membrane which allow H+ ions to pass through. a) How would this affect metabolism? Slow it down – less ATP produced. Would cells consume more or less glucose? More, the enzymes sense how much ATP there is and have to work harder, therefore there needs to be more glycolosis in order to make the original amount of ATP, therefore more glucose is consumed. b) How would the pH in intermembrane space change? proton concentration decreases Mesophyll – top portion of cross section of leaf, where chloroplasts & veins are. Below is a space with pores called stromata, which allow CO 2 in and O 2 out. Shorter wavelength/higher energy/gamma, x-rays, UV longer wavelengths/lower energy/infrared, microwaves, radio waves Photosynthesis: CO 2 + H 2 O [CH 2 O] + H 2 O + O 2 (most basic level) - What is oxydized? H 2 O (O can pull charge close, away from Hs, then bonds with O and has to share e-s so they’re further away) - Reduced? CO 2 (C is making double bonds to oxygen, then makes a single bond to oxygen in CH 2 O, so e-s are closer to the C) - Is ∆G positive or negative? Positive (Oxygen is put in bonded positions that it doesn’t
