A small water plant (elodea) was placed in bright sunlight for five hours as shown. Bubbles of oxygen gas were observed being released from the plant. What substance did the plant most likely absorb from the water for the process that produces the oxygen gas? dissolved nitrogen (3) an enzyme (2) carbon dioxide (4) a hormone Since oxygen gas is being released, it can be inferred that the plant is producing glucose (3) releasing energy from water (2) making protein (4) carrying on active transport

Cellular respiration Plants store solar energy in glucose.

Cellular respiration Plants store solar energy in glucose. Energy released at night (and winter) for cells to use.

Cellular respiration Plants store solar energy in glucose. Energy released at night (and winter) for cells to use. Glucose bonds have too much energy for cells, so it is released as ATP (Adenosine TriPhospate)

Cellular respiration Plants store solar energy in glucose. Energy released at night (and winter) for cells to use. Glucose bonds have too much energy for cells, so it is released as ATP (Adenosine TriPhospate) All cells of All organisms need ATP energy.

Cellular respiration Plants store solar energy in glucose. Energy released at night (and winter) for cells to use. Glucose bonds have too much energy for cells, so it is released as ATP (Adenosine TriPhospate) All cells of All organisms need ATP energy. Autotrophs do both photosynthesis & respiration.

Cellular respiration O2 + C6H12O6 Enzymes ATP + CO2 + H2O Plants store solar energy in glucose. Energy released at night (and winter) for cells to use. Glucose bonds have too much energy for cells, so it is released as ATP (Adenosine TriPhospate) All cells of All organisms need ATP energy. Autotrophs do both photosynthesis & respiration. Heterotrophs ONLY do respiration. The overall reaction is: O2 + C6H12O6 Enzymes ATP + CO2 + H2O

Mitochondria are “powerhouse” organelles that release the energy (make ATP). Glucose + Oxygen ATP Carbon Dioxide Water

Fill in the letters for the overall reaction of cellular respiration. O2 + C6H12O6 Enzymes ATP + CO2 + H2O A B D E Energy Why does this occur in cells?
