Glucose gets into the cells through a process called facilitated diffusion. This is a transport mechanism in which carrier proteins shuttle molecules across the cell membrane without using the cell's energy supplies and so it is called passive transport. The carrier proteins bind to glucose, which causes them to change shape and translocate the glucose from outside of the cell membrane and into the cell.
(a) glucose is important because it is the primary source of energy for the cell.
(b) Glucose is 6 - carbon monomer of starch. It is a sugar.
(c) Glucose is broken down to pyruvate through the process of glycolysis.
Answer:
The last choice.
Explanation:
The molecules would be stored for later use. The cells won't just throw out as molecule they could use later, they will n. it until they need it again.
Answer:
One advantage is that the exoskeleton provides a strong outer layer that acts as armor against predators and environmental hazards. Also serves as a water barrier and provides structure and mobility. disadvantages include less protection and leverage for muscles.
Explanation:
Answer;
Mitochondria and chloroplasts contain their own DNA.
Explanation;
-Mitochondria and chloroplasts have striking similarities to bacteria cells. They have their own DNA, which is separate from the DNA found in the nucleus of the cell.
-From the Endosymbiotic theory, even though both organelles are found in eukaryotic cells, both mitochondria and chloroplast have characteristics often found in prokaryotic cells. These prokaryotic cell characteristics include: an enclosed double membrane, circular DNA, and bacteria-like ribosomes.
