Products and components to other products are made on complex conveyor belts that run along the factory floor. There are two typ
es of conveyor belts in this factory. One type of conveyor belt has many complex machines working along it; the machines are very efficient but only make a few types of products. This type of conveyor belt represents the_____________.
If we apply this analogy to the cellular structures, the type of conveyor belt explained in the question represents the rough endoplasmic reticulum. Because it has a complex structure made up of membrane and ribosomes and it produces only a limited number of proteins just like the very efficient conveyor belt that produces only a few products.
This constancy of the chemicals involved denotes that no particular reaction is taking place on the cells involved. For instance, during photosynthesis it would require CO2, H2O and photons to initiate the process. Thank you for your question. Please don't hesitate to ask in Brainly your queries.
