Answer:
A
Explanation:
The light energy from sunlight in photosynthesis is used to split the water molecule into H+ and O2-. The H+ is then used to reduce NADP+ to NADPH. Through photophosphorylation, the energy from the sun is also used to make ATP from ADP. As the electrons are passed from one protein to the other in the chain, the energy released is what is used to create ATP.
Oxygen is evolved out as a byproduct
NADP+ + 2e- + 2H+ --> NADPH + H+
Explanation:
It correctly reads;
A group of students use a device to study the energy transfer during the chemical reaction between pieces of eggshell (calcium carbon) and vinegar (acetic acid). During the experiment they use the same mass of eggshell but the concentration of the vinegar varies, (1%, 3% and 5%). Answer:
1. Explain why the energy transfer is not the same between the three tests of the experiment.
2. Describe how the device could be modified so that it can MORE ACCURATELY measure the energy transfer in each reaction.
Carbohydrates often receive negative attention as the dieter's enemy. Yet the American Dietetic Association argues that they should be your main source of energy, accounting for 45 to 65 percent of your total daily calories. That's because carbs are your body's quickest fuel source, ultimately yielding the simple sugar glucose. Glucose fuels metabolic reactions throughout your body and is the only form of energy that your brain can use.
Answer:
Plants are mainly multicellular, predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, plants were treated as one of two kingdoms including all living things that were not animals, and all algae and fungi were treated as plants.
