Answer:
b. secondary active transport by a symporter
Explanation:
Glucose is a monosaccharide, one of the digestion products of carbohydrates. Glucose is a polar molecule and can not diffuse through the hydrophobic core of the cell membrane of absorptive cells of the small intestine.
A symporter transports one glucose and two sodium ions from the cavity of the small intestine into the absorptive cells of the villi. Since both Na+ and glucose are transported in the same direction, it is a symport. Here, the energy of the ionic concentration gradient of Na+ serves as a source of energy for glucose transport, the process of glucose transport is secondary active transport.
Answer:
In prokaryotes
Explanation:
The process of photosynthesis probably originated in prokaryotic organisms.
Photosynthesis is the process whereby organisms manufacture their own food in the presence of sunlight, carbon dioxide and water.
- The process is an advancement in the history of evolution of plant species on earth.
- It also furnished a new way of life for other organisms.
- It is widely suggested that some prokaryotes infolded their plasma membrane and it serves as modern day version of chloroplasts.
