Answer:
Photosynthesis stores energy, and respiration releases energy.
Explanation:
When plants doing photosynthesis, they will catch the energy from sunlight. The reaction then will store the energy by making glucose. Glucose has high energy that can be released by doing respiration.
Respiration will break down glucose using oxygen and the energy stored inside glucose is released. The energy will be used to synthesize ATP and ATP will be used as main energy.
Answer:
first 4, then 2, then 1, and lastly 3
Explanation:
First, RNA polymerase binds to the promoter region of a gene on the DNA and initiates transcription. Transcription is the process by which we get mRNA (coding RNA) which is used as a template for protein synthesis. Then, in transcription, the resulting mRNA undergoes modification and maturation. This involves removal of introns, addition of 3'-poly-A tail and 5'-cap. Introns are sequences that do not code for protein and are hence removed. The structure that removes introns is the spliceosome. Thirdly, mature mRNA travels to the cytoplasm. Ribosome (composed of rRNA) binds to mRNA and tRNA to start the process of protein synthesis. The process of formation of protein is called translation. Lastly, the primary structure of protein may undergo folding to form a tertiary structure.
