Please help with this bio question will mark brainliest -recognize the importance of ATP as an energy-carrying molecule
-identify energy sources used by organisms

ATP plays an important role in the transport of macromolecules into and out of the cell. ATP molecules store smaller quantities of energy, but can release energy very quickly.

Organisms get their energy from chemical bonds. Photoautotrophs also use photons of light from the sun as an energy source. Heterotrophs then eat the photoautotrophs and each other to get their energy

It occurs when part of the muscles of the lower leg (gastrocnemius or soleus) are stretched beyond their stability to withstand the tension. This stretching can result in small micro-tears to the muscle fibers or, in a severe injury, a complete rupture of the muscle fibers.
