Herbicides That Act Through Photosynthesis (Beginner Level)

This lesson will examine herbicides that adversely affect light-related processes, thereby causing damage to plants. There are four basic mechanisms that will be studied in this class of agents: herbicides that inhibit or block synthesis of Protoporphyrin IX; herbicides that inhibit synthesis of carotenoids; herbicides that block Photosystem II electron transfer; and herbicides that divert electrons from Photosystem I. All share the ability to cause cellular damage in the presence of light.

La Interacción de la Luz con las Biomoléculas (Beginner Level)

En esta lección se describe la naturaleza de la luz, la energía de los fotones y como dicha energía puede ser transferida a las biomoléculas. Se describen también tanto los procesos benéficos como los procesos dañinos por medio de los cuales las biomoléculas disipan la energía recibida.

Los Pigmentos Vegetales y la Fotosíntesis (Beginner Level)

En esta lección se examinarán las dos principales clases de pigmentos fotosintéticos: las clorofilas y los carotenoides. Se analizarán sus estructuras bioquímicas y su biosíntesis, y se explicará además la organización de estos pigmentos en los sistemas fotosintéticos, que son complejos proteicos que colectan y convierten la energía luminosa en energía química.
