Honors Biology Chapters 5-7 Overview

This set of flashcards covers key concepts from Chapters 5, 6, and 7 of the Honors Biology reading guide, focusing on membrane transport, energy processes, and photosynthesis.

What are three ways that substances can move across a membrane, and which method requires energy?

Three ways are diffusion, facilitated diffusion, and active transport (active transport requires energy).

What are two ways large molecules can move across membranes?

Endocytosis and exocytosis.

How is energy released or stored within a cell?

Energy is released through cellular respiration and stored in the form of ATP.

What is the primary function of enzymes and how do they work?

Enzymes catalyze biochemical reactions by lowering the activation energy required.

What two processes provide energy for life?

Photosynthesis and cellular respiration.

What are the four steps of cellular respiration?

Glycolysis, Krebs cycle, electron transport chain, and oxidative phosphorylation.

Where does photosynthesis occur within the plant?

In the chloroplasts.

How many stages make up photosynthesis?

Two stages: light-dependent reactions and light-independent reactions.

What drives the light reactions of photosynthesis?

Solar energy.

During photosynthesis, what molecules capture solar energy?

Chlorophyll and other pigments.

Where do the light reactions take place within the chloroplasts?

In the thylakoid membrane.
