Student Answer: ERKs increase the life span of osteoclasts and RANKL decreases the life span of osteoblasts. ERKs and RANKL increase the life span of osteoclasts and decrease the life span of osteoblasts. ERKs and RANKL increase the life span of osteoblasts and decrease the life span of osteoclasts. ERKs increase the life span of osteoblasts and RANKL decreases the life span of osteoclasts. Instructor Explanation: In addition to ERKs, RANKL is required for the antiapoptotic and thus longer life span of osteoclasts. These effects increase the life span of osteoclasts (i.e., longer bone resorbing) and shorten the life span of the bone-forming cells, or osteoblasts.
