Hexokinase II (the isoform usually discussed in biochemistry classes as part of glycolysis) catalyzes the frst step in glycolysis. Te isoform of hexokinase that is expressed in most tumor cells is bound to the mitochondrial outer membrane facing the cytosol. Propose two reasons why this would be benefcial to the tumor cell.

The earth consists of a variety of different organisms. despite their diversity, however, some similarities on the structural and metabolic levels may be seen. these similarities can be attributed to a. similarities among organisms in their proteins and nucleic acids. b. the ability of organisms to readily adapt to sudden environmental changes. c. similarities in organisms' habitats and niches. d. the ability of all organisms to interbreed and produce new species.

The circles, or orbits, for electrons are called energy levels. each level can hold only a certain number of electrons. add electrons to each level until you can't add any more. how many electrons can each level hold?

Explain how the number of similarities between the embryos from early stage to late stage is used as evidence of a common ancestry
