Question

Which of the following statements is incorrect

a) Photosynthetic organisms use energy from the sun to synthesize carbohydrate
b) The majority of the solar energy captured by photosynthetic organisms are stored as starch
c) Part of the Solar energy captured by photosynthetic organisms are used to synthesize cellulose
d) Energy stored in both starch and cellulose are eventually released by enzyme catalyzed processes
e) All of the rest are correct statements

Answer 1

The incorrect statement is that all organisms use oxygen and lipids from photosynthesis for cellular respiration. In fact, the primary molecules produced by photosynthesis and used in cellular respiration are oxygen and glucose, not lipids.

Step-by-step explanation:

The statement that is incorrect is 'All organisms perform cellular respiration using oxygen and lipids, which are produced by photosynthesis'. While it is true that cellular respiration involves oxygen, not all organisms use lipids as a primary source for cellular respiration; carbohydrates like glucose are more commonly used. The primary products of photosynthesis are oxygen and glucose, which are then used by most organisms during cellular respiration to produce ATP. Specifically, plants produce glucose through the Calvin cycle.

Photosynthesis is a vital biological process where light energy from the sun is converted into chemical energy, stored in carbohydrates. This energy is essential for the metabolism of both producers (photosynthetic organisms) and consumers (organisms that eat producers or other consumers). The misunderstanding about lipids may arise because, although they are an important energy source, they are not the primary molecules produced by photosynthesis or used in cellular respiration by all organisms.
