Photosynthesis · Botany

The 'light-independent' reactions are so-named because they:

  1. Occur only at night
  2. Do not directly need light
  3. Occur in cells without chloroplasts
  4. Do not require any enzymes
Show answer and explanation

Correct answer: Do not directly need light

Although the Calvin Cycle is often called the 'dark reactions,' it typically occurs during the day. It is 'light-independent' because it uses the chemical products of the light reactions (ATP and NADPH) rather than absorbing photons directly.
