Loss of Rb, an important part of the G1-S transition checkpoint, can result in uncontrolled cell cycle progression and cancer. All of the following would mimic loss of Rb except constitutively active Ras GTPase activating protein. Correct answer: letter E.
Constitutively active Ras GTPase activating protein would not mimic loss of Rb, because it would not directly result in uncontrolled cell cycle progression.
<h3>What is Retinoblastoma (RB)?</h3>
Rb is an important tumor suppressor protein that works to inhibit cell cycle progression by preventing the activation of E2F transcription factors. Constitutively active Ras GTPase activating protein would not directly interfere with the Rb-E2F pathway, which is necessary for uncontrolled cell cycle progression and cancer.

Answer/Explanation:
The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis. the energy storage molecule ATP and the reduced electron carrier NADPH. The ATP and NADPH from the light-dependent reactions are used to make sugars in the next stage of photosynthesis, the Calvin cycle.
