the mitochondria. Aerobic respiration provides a lot of energy needed per molecule of glucose (the level of ATP produced can be as high as 38 ATP molecules per 1 molecule of glucose. When the body is exercising intensely respiration happens faster and the muscles need more oxygen. Anerobic respiration uses a reaction of glucose and water to make energy it creates by-products of water and carbon dioxide (glucose + oxygen → carbon dioxide + water (+ ATP or C6H12O6 + 6O2 → 6CO2 + 6H2O) There will come

absorbs the light and turns it into chemical energy. The plant then uses this energy to carry out photosynthesis. In humans chemical energy found in food is absorbed by the body’s cells during respiration to produce energy. The process of respiration Glucose + Oxygen → Carbon Dioxide + Water + Energy (C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP) This type of respiration is called aerobic respiration which means respiration with oxygen. Mitochondria carry out respiration in the cells. This is why muscles have so

which occurs because of the high blood sugar levels. High blood sugar levels result in an overflow of glucose from the kidneys‚ carrying the fluid along with it. Because there is a constant loss of body fluid through urination there is a constant thirsty feeling (polydipsia). Diabetes is usually accompanied by sudden weight loss‚ due to the body not being able to utilize the available glucose to generate energy. This can result in the individual being hungry throughout the day (polyphagia)‚

and nerve problems can happen to people with diabetes. -What Is Diabetes? Diabetes is a disease that affects how the body uses glucose. When you eat‚ glucose from the food gets into your bloodstream. Then‚ the pancreas makes a hormone called insulin that helps the glucose in the blood get into the body’s cells‚ where it’s used as fuel. When people get diabetes‚ the glucose in their blood doesn’t get into the cells as well as it should‚ so it stays in the blood instead. This makes blood sugar levels

cells. There are three classifications for Carbohydrates: monosaccharides‚ disaccharides‚ and polysaccharides. Monosaccharides are the simple sugars. Two monosaccharides make a disaccharide. Three or more monosaccharides are a polysaccharide. Glucose‚ fructose‚ and galactose are monosaccharides. Sucrose‚ lactose‚ and maltose are disaccharides. Starch and glycogen are polysaccharides. Simple sugars can be found by using Benedict’s test. Starch will react with IKI to give a dark blue color change

little oxygen‚ while proteins (composed of amino acids) have amino groups (-NH3+) and carboxyl (-COOH) groups. These characteristic subunits and chemical groups impart different properties to the macromolecules. For example‚ monosaccharides such as glucose are polar and soluble in water‚ whereas lipids are non-polar and insoluble in water. There are several chemical tests available for the identification of the major types of organic compounds in living organisms. Typically these tests are used to determine

INTRODUCTION Macromolecules are highly important organized organic molecules that are found within living cells. These biological molecules help the body execute precise important tasks. There are four types of macromolecules: carbohydrates‚ lipids‚ proteins and nucleic acids. (Karp‚ 2010) This specific experiment showcased the identification of different macromolecules using three different testing methods. Carbohydrates‚ sugar molecules‚ are known as “fast fuel” in the body‚ and they contain

The word Fermentation haed from Latin (Ferver which means to ‘boil’).As during fermentation there is lot of frothing of the glucose and sucrose when fermented in the presence of yeast cells are converted to ethyl alcohol. During fermentation of starch‚ starch is first hydrolysed to maltose by the action of enzyme diastase. The enzyme diastase isrom gery seeds. Fermentation is
