Chloroplasts were isolated from spinach leaves and placed in a sodium bicarbonate buffer. During a 24 hour period, the chloroplasts received the following dark/light exposure: $$0?08:00$$ hours- dark 08:00-19:00 hours- bright illumination of visible light 19:00-24:00 hours- dark Throughout the treatment, the $$\mathrm{pH}$$ of the thylakoid space was measured indirectly through use of a $$\mathrm{pH}$$ sensitive dye that was monitored on a microscope. Oxygen evolution was also measured in each treatment. During which phase of the experiment would the highest oxygen production occur? $$0?08:00$$ - dark 19:00-24:00 dark 08:00-19:00 bright illumination of visible light During which phase of the experiment would the $$\mathrm{pH}$$ in the thylakoid space be lowest? $$0.08:00?$$ dark 19:00-24:00 dark 08:00-19:00 bright illumination of visible light Question 12 2 pts What would happen to the rate of photosynthesis if the chloroplast were exposed to only green light from 08:00-19:00? The rate would increase. The rate would decrease The rate would not change
