Carbohydrate digestion - mouth and stomach & pancreas and small intestine

By: HWC, Views: 5970

• Digestion of complex carbohydrates (starches and glycogen) involves: • Amylases produced by the salivary glands and pancreas. • Brush-border enzymes in small intestine. • In the mouth, amylase from the parotid and submandibular salivary glands begins carbohydrate digestion. ...

Glucose anabolism reactions: Glycogenolysis and Gluconeogenesis

By: HWC, Views: 6553

• Glucose not needed immediately is stored as glycogen. The process that creates it is glycogenesis. • When ATP is needed for body activities, stored glycogen is broken down by a process called glycogenolysis. • Glucose can be formed through two different anabolic reactions: • Glycog...

Alternative Energy Sources

By: HWC, Views: 393

Points at which organic compounds enter the reaction stages of aerobic respiration. Complex carbohydrates are broken down into simple sugars, such as glucose. They become the substrates for glycolysis. If your body doesn't need to burn glucose for energy, glucose-6-phosphate can be co...

Insulin (glucose uptake by body cells), glycogenesis and lipogenesis

By: HWC, Views: 6356

Insulin is the regulator that allows the sugar from the foods we eat (be it a piece of cake or a stick of celery) to enter our tissues and become part of the metabolic process. Insulin is made by the Islets of Langerhans, which are found in the pancreas of every person. As we previously mentio...

Major Elements in Biological Molecules: Carbohydrates

By: HWC, Views: 5829

Carbohydrates include simple sugars (monosaccharides) as well as large polymers (polysaccharides). Glucose is a hexose, a sugar composed of six carbon atoms, usually found in ring form. A starch macromolecule is a polysaccharide composed of thousands of glucose units. Glucose molecules can be ...

Glucagon (glycogenolysis and gluconeogenesis)

By: HWC, Views: 6126

• Exercise, or not having eaten recently, causes a decline in blood glucose concentration. • Low blood glucose stimulates alpha cells in the pancreatic islets to secrete glucagon. • Glucagon targets liver cells. • Glucagon causes liver cells to undergo: • Glycogenolysis, a proce...

Hormonal feedback loop components & Glucagon (glycogenolysis and gluconeogenesis)

By: HWC, Views: 6073

The endocrine system maintains many body conditions within normal limits with feedback loops. Each endocrine feedback loop maintains homeostasis using the following components: • Stimulus - a change in a body condition. • Production cell - an endocrine cell that produces a hormone after ...

Uterine (menstrual) cycle - phases

By: HWC, Views: 6255

• The uterus goes through a cyclical developmental pattern to be ready for implantation and support of an embryo. • The uterine, or menstrual, cycle is under the control of ovarian horrnones. • The uterine cycle also has three phases: • Menstrual phase • Proliferative phase ...

Summary of female reproductive cycle days 1-28

By: HWC, Views: 6697

■ The first five days of the cycle include the menstrual phase. ■ Progesterone and estrogen levels are low. ■ Menses occurs. ■ GnRH pulses more frequently promoting FSH and LH levels to rise. ■ Primary follicles are stimulated to develop. ■ Days five through thirteen consist o...
