Quizplus · Accepted Answer

Telomeres are protective caps at the end of chromosomes that shorten with age and lifestyle choices. Telomerase is an enzyme that can lengthen telomeres, promoting cellular longevity. Studies have shown that healthy lifestyle choices, such as quitting smoking, reducing alcohol intake, eating a healthy diet, and engaging in regular physical activity, can increase telomerase activity and slow the rate of telomere shortening. Therefore, Lorenzo's lifestyle changes are likely to increase telomerase activity.
