Photosynthesis and Related Biochemical Processes

Flashcards covering key vocabulary related to photosynthesis, biochemical coenzymes, and the structure of chloroplasts.

NADH

A common coenzyme in catabolic reactions, playing a critical role in cellular respiration.

NADPH

A common coenzyme in anabolic/synthesis reactions, important for the Calvin cycle.

Excited Electrons

Electrons that have moved farther out from the atomic nucleus and are no longer in their ground state.

Antenna Pigments

Molecules that capture light energy and transfer it to reaction centers.

Reaction Center Pigments

Pigments that can transfer excited electrons to nearby molecules.

Photosystems

Clusters of proteins and light-sensitive pigments embedded in thylakoid membranes, involved in photosynthesis.

Thylakoids

Internal folded membranes within chloroplasts that contain the light-dependent reactions of photosynthesis.

Stroma

The fluid-filled space outside the thylakoids in chloroplasts, site of light-independent reactions.

Granum (Grana)

Stacks of thylakoids found within chloroplasts, facilitating the light-dependent reactions.

Chloroplast

The organelle in plant cells where photosynthesis occurs, primarily located in leaves.
