Define the following terms: Digestion: Digestion is the breakdown of large insoluble food substances in small and soluble one by means of mechanical and chemical actions. Peristalsis: It is a series of alternate contraction and relaxation of the circular and longitudinal muscles‚ producing a wave-like motion to move food down the oesophagus‚ from the mouth to the stomach. Emulsification: It is the hydrolysis of a few large fat globules into many small and soluble fat molecules. Transpiration:

metabolized in the body! Digestion is the chemical breakdown of food molecules into smaller molecules that can be used by various cells within the body. The breakdown is initiated when food is ingested in the mouth and specific enzymes are exposed to components within the food molecules. Digestion begins in the mouth with mastication‚ or chewing‚ performed by the teeth. The purpose of chewing is to grant the food more exposure to enzymes‚ therefore allowing chemical digestion to occur faster. The presence

Anaerobic respiration in Bacteria Like humans and other animals‚ bacteria need to breathe. Anaerobic bacteria basically mean bacteria that respire anaerobically. All living cells need to respire in order to release energy for vital cell activities. Anaerobic respiration is respiration in the absence of oxygen‚ hence anaerobic bacteria does not breathe at all. The purpose of respiration is to provide the cell with the appropriate molecules for creating energy in the form of adenosine triphosphate

Microorganisms Anaerobic respiration takes place in yeast and some bacteria‚ producing ethanol and carbon dioxide. They have been used in the making of many foods such as bread‚ yoghurt and vinegar‚ Lactic acid bacteria are the key ingredient in yogurt production as they they initiate the fermentation process. Many of the species used in yogurt provide added health benefit to those who eat them regularly and are often referred to as probiotics. Probiotics are believed to strengthen your immune

In fact‚ there are few studies regarding this topic. Rethorst et al (10) conducted a literature review about the antidepressive effects of exercises and presented data that‚ like aerobic‚ anaerobic exercises were potentially equal to reduce depression symptoms. However‚ they did not analyse low intensity anaerobic exercises. Then‚ there is a concern related to what intensity of exercise is more effective. Singh et al (11) showed that a high intensity training (HIT) can produce more results to diminish

(Wright‚ 2007) The formula for cellular respiration is below: Glucose +oxygen = Energy‚ carbon dioxide and water. Carbon dioxide and water are the waste products from creating energy. Respiration can happen without oxygen. This process is called anaerobic respiration. The equation glucose+ oxygen which produces energy along with the bi-products produces 38 Adenosine Triphosphate (ATP). It produces more ATP because it has oxygen present (aerobic) this is used more effectively in the body for things

to function. Respiration comes in two forms – anaerobic and aerobic. Anaerobic respiration refers to respiration without oxygen. A common example of this is swimming as there is no oxygen in water therefore the individual continues to move and exercise without oxygen. This causes oxygen debt which must be repaid once the anaerobic exercise is complete. This is why athletes who exercise in short bursts breathe heavily after. The equation of anaerobic exercise is:- Glucose → Lactic acid + Energy
