Lipophilic hormones,
intuitive as the name suggests, tend to dissolve
well in lipids/fats than they do in water. Therefore lipophilic hormone does not dissolve well in blood plasma which
would affect their diffusion. The carrier proteins are mainly the serum
albumins.
Photosynthesis is the process through which plants use sunlight and carbon dioxide to make food to sustain themselves. Cellular Respiration is when cells use oxygen and water to create a food source for the cell. The formula for photosynthesis is the same for cellular respiration except it's backwards. Hope this helps.
