To get a rough estimate of your heart rate during any form of activity, begin by calculating your maximum heart rate. This rate changes on a year-by-year basis and is possible to determine by subtracting your age from 220. So, if you're a 50-year-old woman, your maximum heart rate is 170 beats per minute.arch to Your Own Beat. Walking, regardless of the distance you travel, is a moderate-tempo activity, according to the Centers for Disease Control and Prevention. Provided you keep your pace during your one-mile walk no greater than 3 mph, your heart should beat at a moderate rate.
View Full Document. Lysosomes are vesicles that contain digestive enzymes. These can fuse with vesicles containing extracelluar material or old organelles, causing the contents to be degraded. Peroxisomes are a subclass of microbodies that carry out oxidative metabolism that generates peroxides. The isolation of these enzymes in vesicles protects the rest of the cell from the very reactive chemistry occurring inside. Vacuoles are membrane-bounded structures that have a variety of roles ranging from storage to cell growth in plants.
Lysosomes can be said to be a cell's digestive system.    â¦    Lysosomes are organelles that contain digestive enzymes They digest excess or worn out organelles, food particles, and engulfed viruses or bacteria. The membrane surrounding a lysosome prevents the digestive enzymes inside from destroying the cell. Lysosomes fuse with vacuoles and dispense their enzymes into the vacuoles, digesting their contents. They are built in the Golgi apparatus.
