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.

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.
95% of your food is composed of carbohydrates, proteins and fats. Digestive enzymes are composed of various amounts of amylase, protease and lipase. Amylase helps in digesting carbohydrates, protease helps in digesting proteins and the lipase helps in digesting fats.These three enzymes play a crucial role. There are also a number of other enzymes that are required for the proper functioning of the digestive system.For example, there are digestive enzymes like lactase, cellulase and sucrose. Lactase helps in the digestion of dairy products and lactose.Cellulase helps in fiber digestion, while sucrase helps in the digestion of starches and sugars. Without digestive enzymes, your body wouldn't be able to digest and breakdown the food it ingests.here are also a number of other enzymes that are required for the proper functioning of the digestive system. For example, there are digestive enzymes like lactase, cellulase and sucrose. Lactase helps in the digestion of dairy products and lactose.
