**Question:**Which is a difference between proteins and DNA?**Options:**- Proteins contain carbon atoms, DNA does not- DNA is found in the cell membrane, proteins are only in the cytoplasm- DNA is mostly contained in the nucleus, proteins are found in nucleus and cytoplasm- Proteins store information, DNA catalyzes reactions**Explanation:**This question asks for a distinguishing feature between proteins and DNA. Consider the properties and locations of biological molecules to identify the correct answer. During the photosynthesis laboratory, we used the leaf disk method for measuring the photosynthetic rate. After 20 minutes of receiving light, leaf disks floated again. The phenomenon occurred because the mesophile (internal layer of leaves):- ○ received water from the solution- ○ trapped water- ○ received a hydrogen ion- ○ produced oxygen

Proteins contain carbon atom DNA does not :- false , because DNA also contain carbon atom as DNA consists of sugars , phosphate group and base and also sugars are the ring of carbon and oxygen atom . As Proteins are the marcomolecules form by amino acid and marcomolecules contain the carbon atom so, this point do not comes under differences. DNA is found in the cell membrane proteins are only in the cytoplasm : false DNA are found in nucleus and the nucleus is an organelle found in eukaryotic cells and also the nuclear envelope surrounds the nucleus and all of its contents. The nuclear envelope is a membrane as similar to the cell membrane. BUT proteins are found in not only cytoplasm. proteins (designated CP for cytoplamsic proteins) are roughly equally concentrated in nucleus and cytoplasm, but—because the cytoplasm is 50 times larger than the nucleus. DNA is mostly contained in nucleus proteins are found in nucleus and cytoplasm :- TRUE ,DNA are found in nucleus and the nucleus is an organelle found in eukaryotic cells and also the nuclear envelope surrounds the nucleus and all of its contents. The nuclear envelope is a membrane as similar to the cell membrane. And proteins are found in not only cytoplasm. proteins (designated CP for cytoplamsic proteins) are roughly equally concentrated in nucleus and cytoplasm, but—because the cytoplasm is 50 times larger than the nucleus. proteins store information and dna catalyzes reaction :-false DNA store the gentic information and protien catalyzes reaction. Received water from the solution :-which help in photosysthesis process to make the process to start. Trapped water :- trap water from the solution and help in coverting the co2 , mineral in water into o2 Received a hydrogen ion :- due to light dependent reaction the splitting releases an electron and results in the formation of oxygen (O2) and hydrogen ions (H+) in the thylakoid space . Produced oxygen as in the process of photosynthesis the formation or production of oxygens is take place . Also Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
