Answer:
D) The hydrogen and oxygen atoms of water are split in the light reactions, and oxygen is released. In the Calvin cycle, hydrogen atoms join with the carbon and oxygen atoms of carbon dioxide to form carbohydrates.
Explanation:
Photosynthesis is the process by which plants produce carbohydrates (sugars) from carbon dioxide in the atmosphere and water using the energy of sunlight. The process of photosynthesis occurs in two stages: (i) the light-dependent stage and (ii) the light-independent stage.
Light reactions: In this stage, the hydrogen and oxygen atoms of water are split in the light reactions, and oxygen is released. Also, the energy storage molecule ATP and the reduced electron carrier NADPH are produced.
Light-independent reaction or Calvin cycle: in this stage, carbon atoms from CO₂ are incorporated into ribulose-5-phosphate and used to produce glyceraldehyde-3-phosphate, a three-carbon sugar using the energy of ATP and NADPH from the light reactions. Essentially, hydrogen atoms join with the carbon and oxygen atoms of carbon dioxide to form carbohydrates.
Answer:
the questionnaire is incomplete, the options are attached to the graph
correct answer c
Paine's experiment was performed when exrtaer the starfish that was considered a negative predator by feeding on a local mussel, what was expected is that by eliminating the starfish it proliferates but its consequence was that it began to displace other species When the mussels became a predator due to the alteration of the ecosystem, the balance was removed and now the species cannot coexist.
The type of behaviour is called agonistic. It is the term for any social behaviour related to fighting.
The correct answer is the last option.
The first option does not make sense as the electron transport chain makes the most ATP from the whole ATP synthesis cycle including glycolysis and the Kreb's Cycle. It also does not make NADH, but instead splits NADH into NAD- and H+. The H+ are used later to make ATP.
The second option also does not make sense as a "lysosome" is a digestive "pocket" in the cell, used for taking in and digesting food for the cell.
The third option also does not make sense as it does not produce NADH and is not during glycolysis. The electron transfer chain breaks up NADH and FADH2 and is the last step in the ATP synthesis process, after glycolysis and Kreb's Cycle.
The last option is correct. The electron transfer chain has the ability to make 34 molecules of ATP (in theory; so in real-life this does not always happen). The electron transfer chain does break down several compounds derived from glucose in a series of chemical reactions that do occur in the cristae of the mitochondrion.
