organic molecules are carbohydrates‚ lipids‚ and proteins. Carbohydrates contain carbon‚ hydrogen and oxygen with a ratio of 1:2:1‚ this means that for every 2 hydrogen atoms there is one carbon atom and one oxygen atom. They are necessary for the body to function properly because they provide the fuel that burns to produce energy. Carbohydrates come in the class of either a monosaccharide‚ disaccharide‚ or polysaccharide. Monosaccharides are the simplest form of a carbohydrate‚ disaccharides are made

We have four important macromolecules; carbohydrates‚ lipids‚ proteins‚ and nucleic acids. From these four‚ the macromolecule I chose for this assignment was carbohydrate. Carbohydrates branch off into three main categories; monosaccharides‚ disaccharides‚ and polysaccharides. I decided to focus on disaccharides‚ specifically sucrose. Sucrose is more commonly known as table sugar. It has a chemical formula of C12H22O11. It is physically described as a white‚ odorless (although when heated‚ it may

Unit 5 Outcome 2 – Energy Metabolism Booklet The Respiratory System The respiratory system consists of the nose‚ mouth‚ pharynx‚ larynx‚ trachea‚ bronchi and lungs. These provide a passageway to allow air in and out of the body. Every cell in the body requires oxygen to survive. The primary function of the respiratory system is the exchange of gases. The respiratory system allows oxygen and carbon dioxide exchange‚ this is necessary to sustain life. During the process of breathing air is inhaled

3 Yeast Metabolism Metabolism refers to the biochemical assimilation (in anabolic pathways) and dissimilation (in catabolic pathways) of nutrients by a cell. Like in other organisms‚ in yeast these processes are mediated by enzymic reactions‚ and regulation of the underlying pathways have been studied in great detail in yeast. Anabolic pathways include reductive processes leading to the production of new cellular material‚ while catabolic pathways are oxidative processes which remove electrons

1 diabetes and is very physically active. An example of a healthy day of eating for Jason would be three meals that do not individually exceed 60 grams of carbohydrates. As for between meals and to promote energy for sports‚ it would be a good idea for Jason to choose nutrient dense snacks that do not contain more than 30 grams of carbohydrates. Some snack suggestions might be a small granola bar‚ nuts and fruit‚ or peanut butter crackers. Jason’s morning meal could be a breakfast burrito that includes

Carbohydrates are a large group of organic compounds which are found in certain foods which contain fibres‚ starches and sugars‚ these include‚ fruits‚ vegetables‚ grains and milk products. Carbohydrates play critical parts in all life shapes even thoughin trendy diets carbohydrates are usually avoided‚ they are still very important for maintaining a healthy lifestyle‚ this is because they are one of the four major classes of biomolecules. (1)One of the roles of carbohydrates is energy production

BIOLOGY HSC NOTES MAINTAINING A BALANCE • Identify the role of enzymes in metabolism‚ describe their chemical composition and use a simple model to describe their specificity on substrates. Enzymes are protein molecules that allow the body to engage in chemical reactions‚ such as metabolism. There activities can be catalytic (being able to control the rate of either increasing/decreasing chemical reaction) Enzymes have a specific shape‚ and this shape must be intact‚ otherwise the effectiveness

Carbohydrates - the Good‚ the Bad‚ the Iffy In the video “Are All Carbohydrates Equally Bad?” Dr. Jason Fung gives us a very good description of how different carbohydrates impact our body. Dr. Fung concluded that fructose‚ a sugar that found in fruits and honey‚ is much worse for us than glucose that found in bread‚ rice‚ and potatoes (Brefere & Drummond‚ 2017‚ p. 68). Even though they are both single sugars‚ they have different effects on our body. The same as people questioned for many years
