What moves against the concentration gradient in biological systems?
In biological systems, active transport moves substances against the concentration gradient.
How do substances move against the concentration gradient in biological systems?
In biological systems, substances can move against the concentration gradient through a process called active transport. This process requires energy to pump molecules or ions across a cell membrane, from an area of lower concentration to an area of higher concentration. This allows cells to maintain specific internal concentrations of substances, even when the external environment has different concentrations.
Do paracellular or transcellular transport systems move substances across simple epithelia?
Paracellular transport systems move substances across simple epithelia by passing between adjacent cells through tight junctions, while transcellular transport systems move substances across simple epithelia by passing through the cytoplasm of the epithelial cells.
What is the purpose of CRISPR systems in prokaryotes and how do they contribute to the defense mechanisms of these organisms?
CRISPR systems in prokaryotes serve as a defense mechanism against invading viruses and plasmids. They work by storing genetic information from previous encounters with foreign DNA and using it to target and destroy similar sequences in future invasions. This helps prokaryotes protect themselves from harmful genetic material and maintain their genetic integrity.
What substances is not carried by the cardiovascular system?
Substances not carried by the cardiovascular system include nutrients absorbed by the digestive system, waste products excreted by the kidneys, and hormones released by endocrine glands. These substances are transported through other systems in the body to reach their intended destinations.
