Which of the following best describes cell communication processes that occur when a cell detects a signaling molecule? A. The cell produces hormones that convert the molecule to an electric signal that is detected by relay molecules
B. The cell releases an enzyme that binds the molcule to receptors, allowing the molcule to enter the cell
C. The molecule binds to a receptor protein, which changes the protein and triggers signal transduction
D. The molecule enters the cell through an ion channel and activates a cellular response by inhibiting tranduction

Neelaredoxin is a 15-kda protein that is a gene product common in anaerobic prokaryotes. it has superoxide-scavenging activity, and it is constitutively expressed. in addition, its expression is not further induced during its exposure to o2 or h2o2 (silva, g., et al. 2001. j. bacteriol. 183: 4413–4420). which of the following statements best describes neelaredoxin synthesis? a-neelaredoxin is produced at all times; levels are constant even when exposed to o2 or h2o2.b-neelaredoxin is produced at all times; exposure to o2 or h2o2 increases expression.c-neelaredoxin is produced at all times; exposure to o2 or h2o2 decreases or prevents expression.d-neelaredoxin is only produced when there is exposure to o2 or h2o2.
