This potential is then used to drive ATP synthase and produce ATP from ADP and a phosphate group. Biology textbooks often state that 38 ATP molecules can be made per oxidised glucose molecule during cellular respiration (2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport system).
Answer: False
Explanation:
Hemoglobin can be defined as red protein that transports oxygen to various parts of the body according to its need.
It does not transports the same amount of oxygen to all the tissues. Some tissues of the body might require more more oxygen and some cells might require less amount of oxygen.
It depends on the state of activity. It transports more oxygen to the tissue that require it the most.
Example: The skeletal muscles of the body require more oxygen and it can be more than 80% .
Hence, the given statement is false and hemoglobin does not releases the same amount of oxygen to each and every tissue of the body.
The water level in the bucket would drop.
This is because the pebbles have a greater density than water - they displace more water (when floating in a cup), than their volume. Thus the water displaced by the cup of floating pebbles has to be more than the volume of pebbles in the cup.
