Answer:
C. only glycolysis and the Krebs cycle
Explanation:
Conversion of 1,3-bisphosphoglycerate into 3-phosphoglycerate and conversion of phosphoenolpyruvate into pyruvate during glycolysis obtains a total of 4 ATP molecules per glucose (2 from each reaction). Here, ATP formation occurs by the transfer of the phosphoryl group from a substrate such as 1,3-bisphosphoglycerate. Therefore, it is called a substrate-level phosphorylation.
Similarly, oxidative decarboxylation of alpha-ketoglutarate into succinyl CoA and conversion of succinyl CoA into succinate forms 2 ATP molecules per glucose during Kreb's cycle. Here, the energy for ATP synthesis is provided by oxidative decarboxylation of a substrate. Therefore, it is also substrate-level phosphorylation.
In terms of the net reactants and products, yes, cellular respiration is the reverse of photosynthesis.
Cellular respiration: Glucose and oxygen are used to make ATP, carbon dioxide, and water.
Photosynthesis: ATP, carbon dioxide, and water are used to make glucose and oxygen.
However, their pathways are NOT the reverse of each other. The enzymes involved are vastly different for each, so only the net reaction is the "reverse."
The answer is A. Sea levels rose over 300 feet
Due to carbon dioxide sunlight get trapped in earth's atmosphere, increases the temperature and results in global warming. Due to this glaciers melt and sea level increases and hence coastal areas may flood. The sun's rays reach us in the form of visible light, and raise the temperature of earth. This heat energy warms the earth then goes back into space, and so the temperature remains in balance.
Answer:
Every sensory neuron is a (an) stimuli to the central nervous system, and every motor neuron is a(an) transmitter from the central nervous system.
