Photosynthesis CO 2 + H 2 O + Energy C 6 H 12 O 6 + O 2 What do you think will happen if the plant was watered, but kept out of the light for several weeks? Consists of adenine, a 5 carbon sugar called ribose, and three phosphate groups. ATP- is one of the most important compounds that cells use to store and release energy. ATP can easily release and store energy by breaking and re-forming bonds between phosphate groups. This characteristic of ATP makes it exceptionally useful as a basic energy source for all cells. Cells use ATP to store and release energy to carry out active transport. Ntt=ATPNtt=ATP Membrane protein that uses ATP to pump sodium ions (Na + ) out of the cell and potassium ions (K + ) into the cell Cells regenerate ATP from ADP as needed by using energy in foods like glucose. Organisms that obtain food by consuming other living things. Some eats plants Some obtain food from plants indirectly by feeding on plant-eating animals. Ex. Cheetah eats a hare Organisms that make their own food. Use light energy from the sun to make their own food. Photosynthesis- conversion of light energy into usable energy in plants stored in the bonds of carbohydrates. CO 2 + H 2 O + Energy C 6 H 12 O 6 + O 2
