Calories are a unit of heat [energy ] to our bodies. Putting food in our bodies is like putting wood [ fuel ] in the fire place.
A cell releases energy when glucose(food) and oxygen come together, then they produce water, Carbon Dioxide, and energy. a simpler form of this is the equation oxygen+glucose=water+carbon dioxide+energy
What is chemical energy? Chemical Energy,example: burning paper,most likely school food and
The process is fermentation.
Plants produce food for themselves during photosynthesis. The process of photosynthesis: CO2 + H2O --> C6H12O6 + O2 The food is glucose.
Oxygen
Respiration.
cellular respiration
The answer is photosynthesis I think.
mitochondria
Mitochondria. These organelles using the electron transport chain are able to produce ATP which is the major energy unit in cells. Mitochondria produce energy from food Chloroplasts- produce energy from sunlight.
The mitochondria in a cell produce energy, but extra energy from food is transformed into fat and put into special fat storing cells to be accessed later.
What must the human body need to get energy from food is to use oxygen to produce ATP which will fuel the cells.
either produce offspring or produce hormones
The organelle that captures energy from sunlight and uses it to produce food for the cell is called a chloroplast.
The energy in food is compressed because of burning process
Compared with burning, cellular respiration is a more controlled fall of electrons- more like a step-by-step walk of electrons down an energy staircase. Instead of releasing food energy in a burst of flame, cellular respiration unlocks food energy in small amounts that cells can put to productive use which is the conversion of food energy to ATP energy.
