Answer:
b. How does food yield energy?
Explanation:
The main question is how energy is produced from food such as carbohydrates, fats and proteins etc. First the carbohydrate is converted into glucose molecule and then glucose is absorbed by the cell and is broken down in the mitochondria of the cell with the addition of oxygen and generate energy in the form of adenine tri phosphate. All the scientists wants to know that how a food is converted into energy.
Because electrons are “pulled” towards the oxygen.
Answer:
"without light energy from the sun, photosynthesis would still occur" is completely false. Light energy is needed for the light-dependent reactions, or simply the light reactions, of photosynthesis.
"oxygen is an input into photosynthesis, carbon dioxide is an output" is also completely false. It is the opposite.
These statements are true, however:
SUNLIGHT
CARBON DIOXIDE
WATER
MINERALS
OXYGEN
PLANT SUGARS
Carbon dioxide enters the leaves through stomata (tiny holes) in the leaves.
Sunlight is an input, CO2 is an input, water is an input (taken in through the roots, transported through the veins), minerals are a collective input, oxygen is an output (produced during photolysis), and plant sugars are an output (glucose, for an example).
An environment high in carbon dioxide and high in oxygen induce oxygen to bind to hemoglobin. Another factors are an environment under high pressure and an environment under low pressure.
