<span>Thylakoids contain the components needed for photosynthesis. They are the flattened sacs in the chloroplast where the membranes where the light reactions take place for photosynthesis, the process by which light energy is converted into chemical energy.</span>
Answer:
No, the light-dependent reactions doesn´t depend on the Calvin Cycle
Explanation:
While the Calvin cycle produces ADP and NADP+, both of which are photophosphorylated by the light-dependent reactions, there is another carbon cycle, called PHOTORESPIRATION, in which the enzyme RuBisCO (RuBP oxygenase-carboxylase), OXYGENATES RuBP (ribulose-1,5-bisphosphate), instead of the CARBOXYLATION OF RuBP (the normal Calvin Cycle), releasing 3CO2 and spending ATP and NADPH (produced by the light-dependent reactions), thus, providing the ADP and NADP+ photophosphorylated by the light-dependent reactions.
PHOTORESPIRATION results in a NET LOSS of fixated carbon, and is activated by certain conditions like HIGH TEMPERATURE and LOWER CO2 AVAILABILITY (due to CLOSED STOMATA as a response to droughts). However, the main functions of this system are not clear. It may be involved in nitrate assimilation, free radicals regulation, plant growth, homeostasis of plant cells, among others.
Exercising doesn't mean you have to spend hours in the gym. Exercises can be done at the comforts of your home too, and there's plenty of exercise available, especially for those who have less time to do so. Just like for example, waiting time. While you are waiting for your clothes in the washing machine to finish, you may use this time to do some basic exercises such as running in place, jumping jacks or carrying weights. It may only take a few minutes, but performing these exercises in less time is better than not doing it at all.
Answer:
I believe I have had this question this before. The correct answer should be rr, BB.
Answer:
They help reduce greenhouse gas emissions, but the downside is hybrid cars require more energy to produce than normal cars
Explanation:
Ok I'll see what I can do. I'll try my best to provide you the correct answer.
