By: HWC, Views: 7435
• Water is the most abundant molecule in ingested fluids. • Water plays a primary role in hydrolytic digestive reactions. • Helps liquefy and transport digestive foodstuffs down the tract. • Transports secretions from accessory digestive organs to gastrointestinal tract. • Aids ...
Cellular Respiration & Glucose Mobilization (Glucose transport & Phosphorylation of Glucose)
By: HWC, Views: 7522
Glucose is completely broken down into CO2 and H2O during the process of cellular respiration, which includes 3 stages: 1) glycolysis; 2) the Krebs Cycle; and 3) the electron transport chain. Glucose enters this energy yielding pathway of cellular respiration in the first stage known as...
Antidiuretic hormone (vasoconstriction, water reabsorption & sweat inhibition)
By: HWC, Views: 7602
• Dehydration, blood loss, and low amounts of water in the blood can cause blood volume and pressure to decrease. • Neurosecretoxy cells in the posterior pituitary release antidiuretic hormone(ADH). • ADH binds to smooth muscle cells in blood vessel walls, stimulating them to vasoconstr...
Covalent bonds - role in the body
By: HWC, Views: 7702
A covalent bond is formed when atoms share one or more pairs of electrons. This is opposed to an ionic bond, where electrons are actually transferred from one atom to another. Formation • Atoms fill up the outer orbital by sharing electrons. • Two oxygen atoms sharing electrons form on...
Osmosis - Isotonic, Hypotonic, and Hypertonic Solutions
By: HWC, Views: 7825
Isotonic: Equal Water moves in and out of the cell at an equal rate. The cell remains unchanged. Hypotonic: "hypo" hippo Water moves into the cell, making it swell and get fat (like a hippo). Eventually the cell can rupture and burst (aka lyse). Hypertonic: "like a raisin" Water leaves...

Osmosis is when a solvent, such as water, moves from a low-solute concentration solution to a higher-solute concentration solution through a semipermeable. Osmosis is an example of diffusion (a special case of diffusion) in which the molecules are water, and the concentration gradient occurs a...

■ The complete oxidation of one glucose molecule produces the following ATP molecules in each step. • Glycolysis; • Formation of acetyl CoA; • Krebs cycle; • Electron transport chain. ■ In addition, glucose catabolism produces six CO2 molecules and water.
