What are the Parts of a Plant Cell?

By: HWC, Views: 993

Every chloroplast in a plant cell is packed with stacks of flattened sacs called thylakoids. The thylakoid membranes contain chlorophyll, as well as most of the other components required for the light reactions of photosynthesis. The chlorophyll-containing structures within the membranes are c...

Mitochondrial Structure & ETC Protein Complexes (Protein Complexes and Electron Transport)

By: HWC, Views: 1455

The energy carrying molecules, NADH and FADH2, that were generated in glycolysis and the Krebs cycle, now are processed in the mitochondria where their high energy electrons are deposited in an electron chain complex located in the inner mitochondrial membranes. These high-energy electrons now dr...

Types of antimicrobial substances (interferons & complement protein)

By: HWC, Views: 1867

• Found in blood and interstitial fluids. • Discourage microbial growth. • Include interferon and complement proteins. • Produced and released by virus-infected lymphocytes. • Enter new cells and inhibit viral replication. • Act against a large variety of viruses (non-speci...

Michaelis–Menten equation & Kinetic parameters

By: HWC, Views: 1780

The Michaelis–Menten equation is the rate equation for a one-substrate enzyme-catalyzed reaction. This equation relates the initial reaction rate (v0), the maximum reaction rate (Vmax), and the initial substrate concentration [S] through the Michaelis constant KM—a measure of the substrat...

Steps of glucose catabolism

By: HWC, Views: 1943

• During digestion, complex carbohydrates are hydrolyzed into monosaccharides, primarily glucose. • The catabolism of glucose is the primary source of energy for cellular production of ATP. • The anabolism of glucose is important in regulating blood glucose levels. • Glucose cat...

Wound Care

By: Administrator, Views: 4860

Wound healing is a complex process in which the skin, and the tissues under it, repair themselves after injury. In this article, wound healing is depicted in a discrete timeline of physical attributes constituting the post-trauma repairing process.

Physiology of Asthma

By: Administrator, Views: 4830

Asthma is a common chronic disease worldwide and affects approximately 26 million persons in the United States. It is the most common chronic disease in childhood, affecting an estimated 7 million children. The pathophysiology of asthma is complex and involves airway inflammation, intermittent ai...

Types of energy transfer reactions: oxidation-reduction reactions and ATP generation reactions

By: HWC, Views: 2010

■ Metabolism balances anabolic and catabolic reactions. ■ Anabolism is energy transfer from ATP to simpler molecules in order to build them up into larger, more complex molecules. ■ Catabolism is breaking down larger, more complex molecules, usually to transfer energy from them in order...

ETC Protein Complexes & Chemiosmosis (Total ATP Production and ATP Synthase)

By: HWC, Views: 1570

You will notice that FADH2 donates two electrons further downstream than NADH. This results in only two protons being pumped across the inner membrane. The final electron acceptor for these transported electrons is oxygen. Oxygen receives these electrons, plus protons from the aqueous matrix. ...
