They are called Tracers ;)
Answer:
The correct choice is ''ion electrochemical gradients''.
Diffusion of ions across membranes through specific ion channels is driven by <u>ion electrochemical gradients</u>.
Explanation:
An electrochemical gradient can be considered as that electrical (electrostatic pressure) and chemical (diffusion) force that determine the movement of molecules and ions across the membrane. This electrochemical gradient, in addition to causing movement of substances through cell membranes, is also a type of potential energy available for the performance of different cellular activities, potential energy called membrane potential.
Photosynthesis is which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Cellular respiration is a set of metabolic reactions and processes that take place in the cells. they work to gather by Photosynthesis<span> makes the glucose that is used in </span>cellular respiration<span> to make ATP.
Just remember to put it in your own words though. : )

Protein synthesis is accomplished through a process called translation. After DNA is transcribed into a messenger RNA (mRNA) molecule during transcription, the mRNA must be translated to produce a protein. In translation, mRNA along with transfer RNA (tRNA) and ribosomes work together to produce proteins.
