Question

4 multiple choice 1 point a protein that is temporarily associated with a biological membrane is a(n): transmembrane protein peripheral membrane protein transmembrane protein and an integral membrane protein integral membrane protein 5 multiple choice 1 point the transition state is that portion of the progress of a chemical reaction with a large amount of energy found in ____ reactions. non - spontaneous endergonic exergonic both endergonic and exergonic 6 multiple choice 1 point which one of the types of proteins interacts directly with a stop codon? trna release factor sigma factor elongation factor translation termination factor

Explanation:

• For question 4: Peripheral membrane proteins are temporarily associated with the biological membrane, while transmembrane and integral membrane proteins are more permanently associated.
• For question 5: The transition - state with high energy is present in both endergonic (energy - absorbing) and exergonic (energy - releasing) reactions.
• For question 6: Release factors interact directly with stop codons during translation to terminate the process. tRNA brings amino - acids, sigma factor is involved in transcription initiation, elongation factor is for translation elongation, and translation termination factor is a more general term with release factor being the key player in stop - codon interaction.

Answer:

1. B. peripheral membrane protein
2. D. both endergonic and exergonic
3. B. release factor
