Which statement best describes photosynthesis and respiration? Define the following terms from the question above: Autotrophs, heterotrophs. Rewrite the question in your own words. What are they really asking? What is the correct answer and WHY? If a cell is producing lactic acid, what molecule is most likely unavailable to that cell?
Understand the Problem
The question is inquiring about the concepts of photosynthesis and respiration, specifically asking for definitions of autotrophs and heterotrophs, a rephrasing of the question in simpler terms, and an explanation of the correct answer to a related question about lactic acid production in cells.
Answer
Oxygen is likely unavailable if a cell produces lactic acid.
Autotrophs perform photosynthesis, capturing light energy to synthesize glucose, while heterotrophs rely on consuming organic matter. Both undergo respiration. The question asks about the correct understanding of these processes and their link to autotrophs and heterotrophs. Oxygen is likely unavailable if a cell produces lactic acid, leading to anaerobic respiration.
Answer for screen readers
Autotrophs perform photosynthesis, capturing light energy to synthesize glucose, while heterotrophs rely on consuming organic matter. Both undergo respiration. The question asks about the correct understanding of these processes and their link to autotrophs and heterotrophs. Oxygen is likely unavailable if a cell produces lactic acid, leading to anaerobic respiration.
More Information
Autotrophs like plants use photosynthesis to make food, while both autotrophs and heterotrophs perform cellular respiration to break down glucose for energy. The production of lactic acid indicates a shift to anaerobic respiration due to a lack of oxygen.
Tips
A common mistake is confusing autotrophs and heterotrophs. Autotrophs synthesize their own food, while heterotrophs consume other organisms.
