Answer:
Tidal power, solar power, energy, wind power, biofuel, and hydrogen are six alternative energy sources.
Movement of substances can be classified as active transport of passive transport.
In passive transport movement of substances across the membrane occurs without the expense of ATP. It occurs usually along the concentration gradient i.e., from high concentration to low concentration.
In active transport, movement of substances require energy in the form of ATP because it happens against the concentration gradient i.e. from low concentration to high concentration.
Answer:
A represents photosynthesis and B represents cellular respiration.
Explanation:
As in A there is utilization of carbon dioxide and water to make oxygen and glucose which is a key process of photosynthesis, and then this oxygen and glucose is used as energy source to produce carbon dioxide and water as by products of respiration.
Answer:
Cell respiration begins with Glycolysis
.
Explanation:
Glycolysis is the first and initial step in the cellular respiration. Cellular respiration is the anaerobic process, which takes place in cytosol of the cells. Two molecule of pyruvate(CH3COCOO-) are formed from 1 molecule of glucose(C6H12O6)through glycolysis. The NADH and ATP are high energy molecules formed when the free energy are released. It is the process which takes place through a series of ten enzyme catalysed reactions. 10 enzymes are required to break down the sugar molecule. It occurs in cytoplasm.
