2022 Live Review 1 | AP Biology | Chemistry of Life, Cell Structure, and Function

In this AP Daily: Live Review session, we will review the properties of water and how changes in macromolecule structure can lead to changes in function.
We will highlight two topics in Unit 1: Chemistry of Life. We will review Topic 1.1, addressing how the properties of water result from polarity and hydrogen bonding and describing characteristics of a biological concept. Our Topic 1.5 review addresses how changes in the subunits of a polymer may lead to changes in structure and function of a macromolecule and predicts the effects of a change in a component of biological systems. We will also highlight four topics in Unit 2: Cell Structure and Function. We will review Topic 2.2, addressing how living systems are organized in a hierarchy and making a scientific claim. We will also look at Topic 2.3 and the complex organization of living systems that requires the constant input of energy and the exchange of macromolecules. While looking at that content, we will review how to represent relationships within biological models. The session covers Topic 2.8 and addresses why cells have membranes that allow them to establish and maintain internal environments that are different from their external environments. Within that context, we review how to construct a graph, plot, or chart. We will also review how to calculate surface area to volume ratio and water potential. We will also study Topic 2.9, which covers the processes that allow ions and other molecules to move across membranes. We will review how to explain biological concepts and processes during our discussion of this topic.
