e)all of it
Why are plants that consume 30 ATP molecules to produce one molecule of glucose (rather than the usual 18 molecules of ATP per glucose molecule) favored in hot climates but not in cold climates? What role does temperature play?
As scientists research and develop biofuels, they are faced with many tradeoffs. A plant's usefulness for biofuels depends on how much energy can be collected from the plant matter. In addition, growing plants on a large scale requires energy—such as the gasoline and power needed to run tractors and other harvesting equipment or the energy needed to create and distribute fertilizers and pesticides. An efficient biofuel would maximize the ratio of energy output to energy input.
The following graph illustrates the results of a 10-year study analyzing three different crops used in biofuel production. The data show how much energy was required to grow each crop on 1 hectare of land (energy input) and how much energy was recovered from the total crop on each hectare of land (energy output). A hectare is a measurement of an area of land and is roughly the same as 2.5 acres.
What was the estimated energy input of the grass?
A. 2 kcal × 106
B. 4 kcal × 106
C. 8 kcal…
