Match each of the following organelles with the correct description. Ribosomes nucleus cytoplasm lysosomes Ribo - funtion in protein synthesis nucleus - contains genomic content cyto - constitutes the open volume lyso - contains hydrolytic enzymes Briefly explain how a Scanning Electron Microscope (SEM) forms an image of subcellular organelles, substrates, and viral particles. An image is formed from the interactions of electrons as they reflect off (not through) the surface of...

What is cellular metabolism? - a controlled set of biochemical reactions that occur in living organisms in order to maintain life What is an enzyme? - a protein, or group of proteins, that catalyze (speed up) chemical reactions What is unique about enzymes? - the enzyme is not consumed during the reaction and can be used repeatedly by the cell What is a cofactor? - a small chemical component, usually metal ions, that assist enzymes during the catalysis reactions Do cofactors serve as regu...

Amensalism -/0 interactions - : one species is harmed while the other is unaffected Tend to be more accidental than other relationships Example: a herd of elephants that crushes plants and insects while moving through a forest . Commensalism +/0 interaction: - one species benefits while the other is unaffected Brown-headed cowbirds follow grazing cattle and bison, foraging on insects flushed from the vegetation. Cattle convert plants into dung, which dung beetles can use. Dung beetles dispe...
