The combustion of sugar is a reaction between sugar and oxygen that results in carbon dioxide and water. A combustion reaction requires a large energy input to begin. How does the cell overcome the need for large energy input to begin the reaction of glucose and oxygen during cellular respiration? Choose the correct answer.
A: Enzymes lower the amount of energy necessary to begin the reaction of glucose and oxygen.
B: Enzymes physically break apart and recombine the glucose and oxygen molecules so no energy is needed for the reaction.
C: The cell creates new energy to begin the reaction between glucose and oxygen.
D: The cell uses energy from sunlight to begin the reaction between glucose and oxygen.

How do temperature and salinity affect deepwater currents? question 15 options: as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
