Adenosine Tri Phosphate

Post by Sanjin Kulenovic on June 24, 2014

Hi Nehlia, nice lecture, although at example 1, you made a mistake by putting energy in the left side of the respiration equation. Also, previously, while talking about ATP, you could have introduced it as an energetic molecule that it is, called Adenosine Ari Phosphate, which is made inside the cells. Hope my comments can help.

I thought that chlorophyll absorbs all frequencies of light *except* for green. It reflect the green frequency, which is why we see it as green. If it absorbed green, we'd see it as other colors, not green.
