In DIRE need of help (will mark brainliest) Enzymes are essential to the metabolic processes of a cell. Without enzymes, living organisms could not carry out chemical reactions at a speed that would sustain life.

A) Describe the structure and function of enzymes. Include a discussion of "induced fit".

B) Design an experiment by which you could test how adding increasing quantities of substrate would affect the rate of the enzymatic reaction. Predict what the results of the experiment would be and why.

In which of the following ways is the function of the surface of a microsphere similar to the function of an actual cell membrane? a.both make it possible for the conditions in the interior to be different from the conditions outside. b.both provide a barrier that keeps water from flowing across it so the interior remains dry. c.both separate the rna that forms in the interior from any rna that might form in the environment. d.both can actively move molecules into the interior or out into the surrounding environment.

How do tides affect the organisms living in intertidal zones? a. no organisms live in intertidal zones due to the tumultuous environment. b. the mechanical forces of the waves keeps the organisms clean. c. only plants live in intertidal zones because the animals float away with the waves and never return. d. the mechanical forces of the waves can dislodge the organisms from their habitat.
