Your baby has a good sense of smell from the start. She gets to know your scent on Day 1 and probably recognizes the scent of other people in her life within about a week. Babies are especially sensitive to the smell of breast milk and can even distinguish it from formula , says Dr. Tapas.
As an intermediate pathway between the phosphagen and aerobic system, anaerobic glycolysis can produce ATP quite rapidly for use during activities requiring large bursts of energy over somewhat longer periods of time (30 seconds to three minutes max, or during endurance activities prior to steady state being achieved).
Anaerobic exercise consists of brief intense bursts of physical activity, such as weightlifting and sprints, where oxygen demand surpasses oxygen supply. While aerobic exercise relies on oxygen, anaerobic exercise is fueled by energy stored in your muscles through a process called glycolysis. Glycolysis is a method by which glycogen is broken down into glucose, also known as 'sugar' and is converted into energy. Glycolysis occurs in muscle cells during anaerobic exercise without the use of oxygen in order to produce energy quickly, thus producing lactic acid, which causes your muscles to fatigue. Lactic acid is a by-product of glycolysis and forms when your body breaks down glucose for energy when oxygen is low.
