Replication is important in science so scientists can “check their work.” The result of an investigation is not likely to be well accepted unless the investigation is repeated many times and the same result is always obtained.
Electron transport chain
the electron transport chain. Their energy is used to pump H+ ions from outside to inside the thylakoid against a concentration gradient. The H+ ions build up inside the thylakoid. Electrons move on to photosystem I.
Answer:
From the given information, the transport of glucose in blood across the red blood cells takes place by facilitated diffusion, that involves the spontaneous passive-transport with the help of trans-membrane proteins or transporter proteins to move the ions or molecules down the concentration gradient.
While the transport of glucose in intestines take place via active transport mechanism. It takes place from gut into intestines. It occurs against the concentration gradient with the help of energy molecules like proteins.
