To find the correct answers to the questions, you can use your knowledge about cellular respiration and the processes involved. Here's how:
1. The stage of cellular respiration during which most ATP is made is the Electron Transport Chain. You can eliminate the other options by knowing that ATP is generated through oxidative phosphorylation in the final stage of cellular respiration.
2. The anticodon is part of a tRNA molecule, while the codon is part of an mRNA molecule. You can remember this by understanding that tRNA carries anticodons that pair with the codons on mRNA during protein synthesis.
3. The phase of cellular respiration that does not require oxygen is glycolysis. Remember that glycolysis is the initial step in cellular respiration and can occur in the absence of oxygen.
4. A high concentration of H+ (protons) is found in the Mitochondrial Intermembrane Space. This is due to the movement of protons during electron transport and is essential for the synthesis of ATP.
5. The process/event that is correctly matched to the phase is: tRNA delivers amino acids during Translation. This is because the role of tRNA is to carry specific amino acids and match them with the codons on mRNA during protein synthesis.
By understanding the processes and concepts involved in cellular respiration and protein synthesis, you can determine the correct answers to these questions.
