BIO.2 The student will investigate and understand that chemical and biochemical processes are essential for life. Key ideas include
water chemistry has an influence on life processes;
macromolecules have roles in maintaining life processes;
enzymes have a role in biochemical processes;
protein synthesis is the process of forming proteins which influences inheritance and evolution; and
the processes of photosynthesis and respiration include the capture, storage, transformation, and flow of energy.
Carbon and other elements play a key role in determining the structure and function of macromolecules needed to sustain life processes. Life processes include growth and repair, reproduction, gas exchange, metabolism, and response (BIO.2 b).
Cells make a variety of macromolecules needed for life processes from a relatively small set of monomers. These macromolecules include carbohydrates, proteins, nucleic acids, and lipids (BIO.2 b).
Carbon, hydrogen, and oxygen from sugar molecules may combine with other elements to form amino acids and/or other large carbon-based molecules (BIO.2 b).
In order to meet this standard, it is expected that students will
recognize that living cells are composed of relatively few elements (BIO.2 b)
differentiate the four major categories of macromolecules (lipids, carbohydrates, proteins, and nucleic acids) through their primary roles and functions (BIO.2 b)
