Photosynthesis Steps and Interdependencies

Vocabulary flashcards detailing the required inputs, measurable products, and herbicide inhibition effects for each step of photosynthesis.

Light absorption (chlorophyll)

requires light

to produce ATP and NADPH;

blocking this step with a herbicide results in decreased ATP/NADPH.

Photosystem II

requires light and water

to produce oxygen;

blocking this step with a herbicide results in decreased oxygen.

Electron transport chain

requires electrons

to produce ATP;

blocking this step with a herbicide results in decreased ATP.

Photosystem I

requires light and electrons

to produce NADPH;

blocking this step with a herbicide results in decreased NADPH.

ATP synthase

that requires protons

to produce ATP;

blocking this step with a herbicide results in decreased ATP.

Calvin cycle

requires ATP, NADPH, and $CO_2$

to produce G3P > Glucose

; blocking this step with a herbicide results in decreased G3P.
