![]() ![]() In photosynthesis, the ATP is diverted toĬarbohydrate production for long-term energy storage.Īnimals, of course, benefit from this process indirectlyīecause they can also use carbohydrates as a source of energy. Sources via glycolysis and the citric acid cycle.įigure PS1.1. TheĬarbohydrates can be stored, long-term, and later they can be used as energy They keep happening even without sunlight. ThisĬonversion happens in a series of reactions called "dark reactions", because Carbon dioxideįrom the air is incorporated into carbohydrate molecules. ![]() However, the production ofĪTP in photosynthesis is also connected to carbon capture. They could get the immediate benefit of portable ATP molecules Plants, algae, and some bacteria are capable of carrying out To production of ATP, the biological battery pack. Absorption of photons from the sun is coupled Power uphill steps in biochemical reactions.įigure PS1.1. Remember, ATP is like a portable battery pack in biology it can travel to different parts of a cell where it can be used to In photosynthesis, light energy is absorbed and used to makeĪTP. However, sunlight isĪn even more abundant source of energy over most of the earth's surface. Volcanic vents, such as methane and hydrogen sulfide. In the oceans, some marine organisms get their energy from gases released from Sometimes, all that heat and gas finds its way to the earth's surface in the form of Of heat and drive the conversion of some minerals into gaseous products forĮxample, metal sulfides such as zincblende can be converted to gaseous hydrogen sulfide, H 2S. In biology, energy is needed in order to drive all sorts ofīiochemical processes. ![]()
