One primary function of the cell membrane is

• regulating the flow of simple sugars into or out of the cell

• synthesizing substances by breaking down cell organelles

• storing carbohydrates, water, and starches for future use

• digesting carbohydrates, fats, and protein

Autotrophs differ from heterotrophs in that only autotrophs

• require carbon dioxide for cellular respiration

• 
  release oxygen as a product of cellular respiration

• synthesize nutrients using carbon dioxide and water

• break down sugars to assemble other molecules

• oak tree → leaf → guard cell → chloroplast

Which of the following sequences shows a decreasing level of complexity?

In which cell structure is energy extracted from nutrients?

• chloroplast

• ribosome

• mitochondrion

• vacuole

A fully functioning enzyme molecule is arranged in a complex three-dimensional shape. This shape determines the

• 
  specific type of molecule it interacts with during a reaction

• rate at which the enzyme breaks down during a reaction it regulates

• pH of all body systems

• temperature of the products of the reaction it regulates

Carbon dioxide and oxygen are important resources in ecosystems and are

• recycled through the activity of living and nonliving systems

• stored in the animals of the ecosystem

• lost due to the activities of decomposers

• released by the process of photosynthesis
