Many commercial herbicides act by inhibiting photosynthetic electron transport. They are investigating three herbicides for potential inhibitors of photosynthetic electron transport.
a) How can you determine whether these substances have an inhibitory effect on photosynthetic electron transport? How can you quantify the effect?
b) An inhibitor has produced a strong effect in "in vitro" tests, but the effect is significantly less in "in vivo" tests. What can be the reason for the reduced effect "in vivo"?
It is biochemical reactions that enable organisms to harness sunlight to manufacture organic molecules?
It is a molecule whose high energy phosphate bonds power many biological processes?
This is a disk-like structure that makes up the inner membrane of a chloroplast?
These are plant pigments responsible for bright red, yellow and orange colors in many fruits and vegetables?
These are photosynthetic pigments efficient at absorbing orange, red, yellow, and green light, wavelengths that are not well absorbed by chlorophyll a?

TRUE OR FALSE A coupled reaction is a pair of reactions, one exothermic and one endothermic. ATP contains less energy than ADP. In the ATP-ADP cycle, when the phosphate is removed, energy is released. In coupled reaction, an endothermic reaction supplies the energy needed to drive an exothermic reaction.

Start with a photon of sunlight and a carbon atom in a molecule of carbon dioxide in the atmosphere: model/diagram their pathway from that starting point to their final destination as a glucose molecule that is used for energy in a cell in the plant root.

In the process of aerobic respiration, animals and plants release energy from sugar and oxygen and produce carbon dioxide and water.

- CHCASE Dashboard A student conducts two experiments to observe the effects of different factors on ATP production during aerobic cellular respiration. In the first experiment, the student isolates mitochondria in a test tube, adds oxygen to the test tube, and measures the amounts of ATP produced at three temperatures. In a second experiment, the student keeps the temperature the same and varies the concentration of oxygen added to the test tube for each trial, The student records all data in the table shown.
