How do most cells regulate the activity of enzymes? What enzymes serve as catalysts in metabolism? What does mechanical digestion in the stomach involve? How do villi absorb nutrients? What is the advantage of having enzymes catalyze chemical reactions in living cells?
Why are cells important to living things? Why can't cells store extra free energy? Why it is beneficial for cells to be small? What happens if a cell has no active telomerase? Why do plants have mitochondria? Why is cellular respiration necessary for living organisms?
Question: What do enzymes have that determine their function? Enzyme Function: The function of an enzyme refers to the kind of reaction it can catalyze. Most enzymes can only catalyze one reaction. However, others, like the plant carbon fixation enzyme Rubisco, are capable of catalyzing more th...
Professor: OK.Just before the end of the last class, we started talking about trace metals, metals found in living organisms in very small quantities that serve an important biological, important nutritive function in those organisms.And one trace metal that serves a nutritive function is zinc. ...
Living cells have an enzyme that removes the AM portion, traps the calcein within the cell and allows the calcein to bind calcium so that it fluoresces green under ultraviolet light. Dead cells no longer have this enzyme. Therefore, living cells will fluoresce green, and dead cells will not...

All the arguments concur that de-N-glycosylation enzymes have an important role in plant cells and confirm that the N-glycosylation/de-N-glycosylation system should occur more commonly than presently recognized in living organisms. 展开 关键词: de-N-glycosylation PNGase ENGase ...
At first, these fungi subsist as biotrophs, growing between the plasma membrane and the cell wall of living cells, and switch later to a necrotrophic phase, killing all the colonized cells and utilizing the dead tissues for nutrients. Those parasites found consistently with a given plant disease...

Cells are the basic building blocks of life. Less poetically, they are the smallest units of living things that retain all of the basic properties associated with life itself (e.g., protein synthesis, fuel consumption and genetic material). As a result, despite their tiny size, cells have ...
