Glucose is split into two molecules called pyruvate and two ATP molecules are generated per molecule of glucose as well as two molecules of NADH. Also Glucose takes place in the cytoplasm of the cell. Glycolysis can occur with or without oxygen. Without oxygen it is called fermentation with oxygen it is the first stage of the cellular respiration. • What is the role of the citric acid cycle?
Once this molecules binds in the Krebs cycle it forms tricarboxylic acid and citric acid. When the coenzymes bind it enter into the electron system. While there ATP is then released as energy throughout the body. B. Compare three features of saturated and unsaturated fatty acids.
Both ATP and NADPH are responsible for the reduction of glycerate-3-phosphate into triose phosphate, which is converted into many useful organic compounds like carbohydrates, mainly glucose. Although glucose can be used as a direct energy source by plants, it cannot be used directly by animal cells as a source of energy. Instead, cells use ATP as their immediate source of energy. The conversion
The monosaccharides are them absorbed into the bloodstream. From blood, the monosaccharides are carried to the liver and converted into glucose and then stored in the liver or sent back out to feed the individual cells. Any fiber continues to the large intestine where some is metabolized by bacteria, but most is excreted. Fat From the mouth, chewing food breaks it down to a degree. The lingual lipase, found in saliva, plays a minor role in breaking down fat.
Controlled Variables. temperature; pH; sucrase + sucrose incubation time 4. Describe what is measured as an indicator of sucrase activity and why this is an indicator of sucrase activity. The amount of product produced is an indicator of sucrase activity. This is an indicatore because sucrase is an enzyme found in the small intestine that catalyzes the splitting of the disaccharide sucrose into the monosaccharides glucos and fructose.
Carbohydrates are formed of carbon, oxygen, and hydrogen as the basics. In the body, carbohydrates are converted to glucose, used for energy throughout the body. Carbohydrates can be either simple or complex, and high-glycemic or low-glycemic. Examples of foods containing simple carbohydrates include fruits, vegetables, and dairy products. Breads and cereals contain complex carbohydrates, along with legumes.
How is energy produced? Aerobic respiration, during this a respiratory substances, glucose for example is split in the presence of oxygen and releases carbon dioxide and water. Many ATP molecules are produced which then release energy from the glucose. C6 H12 O6 + 6O2 = 6CO2 + 6H2O +36ATP Lactate is when glucose is converted during anaerobic respiration; the ATP yield will be low. C6 H12 O6 = 2C3 H6 O3 + 2ATP (lactate) This is a structure of ATP ATP contains sugar which is Ribose, a base which is Adenine and three phosphate groups.
Three basic stages in the Calvin Cycle are: fixation, reduction, and regeneration. When in the stroma, there are two other molecules to start up the Calvin Cycle abbreviated as RuBisCO and RuBP. RuBisCO converts a six-carbon compound into a two three-carbon compound called carbon fixation. In conclusion, Calvin Cycle takes in CO2 from their surroundings and photosynthesis makes a cycle that uses the process of cellular respiration. Works Cited Alberts, Bruce.
Diffusion helps to remove dissolved carbon dioxide from the blood and into the expelled air from lungs. Diffusion is the molecules (gas or liquid) moving from high concentration to low concentration. M1: Discuss the role of energy in the body. Our bodies need energy to work properly. The energy we need and use comes from the type of foods we eat.
When energy is required by respiring cells, glucose is absorbed or assimilated in the small intestine where other biological molecules also being absorbed such as amino acids and useful fats. The structure of small intestine helps the absorption of glucose more efficient in such a way of the presence of microvilli which are fingerlike projection of membrane on the surface of the small intestine. These microvilli has a very large surface area to volume ratio so as Fick’s Law states the rate of diffusion is directly proportional
