The drug “dinitrophenol” (DNP) was prescribed by some physicians in the 1940’s to help patients lose weight. This unsafe method was abandoned after a few patients died. DNP uncouples the chemiosmotic machinery by making the lipid bilayer of the inner mitochondrial membrane leaky to H+. Explain how this could cause weight loss. In chemiosmosis‚ NADH are passed along the electron transport chain‚ with energy used to pump protons across the inner mitochondrial membrane. As the protons are transferred

Flatworms ( phylum Platyhelminthes) and roundworms ( phylum Nematoda)‚ but there are many similarities and differences between these two types of organisms. Similarity: • There are many similarities between the two groups of worms‚ Platyhelminthes and Nematoda.

Describe the cell cycle. Include in your discussion the role cyclins and CDKs play in controlling this cycle. The cell cycle is a process that cells undergo to grow‚ reproduce‚ and divide to make 2 daughter cells. The cell cycle has different stages including G1‚ S‚ G2‚ and the M phase. Also we have the G0 phase. There are checkpoints that control the transitions between the phases of the cell cycle in which the process is regulated by cyclins and cyclin-dependent kinases (CDKs). G1 is known as

this essay I will include information regarding: cell differentiation‚ the functions of various cell organelles‚ tissues and a comparison of different tissue types. Cellular differentiation is the process by which a less specialised cell becomes a more specialised cell type. Differentiation happens a number of times during the development of a multicellular organism as the organism changes from a fertilised egg cell to a complex system of tissues and cell types. Differentiation dramatically changes

technology. CELL RELAY Cell relay refers to a method of statistically multiplexing small fixed-length packets‚ called "cells"‚ to transport data between computers or kinds of network equipment. It is an unreliable‚ connection-oriented packet switched data communications protocol. Cell relay transmission rates usually are between 56 kbit/s and several gigabits per second. ATM‚ a particularly popular form of cell relay‚ is most commonly used for home DSL connections‚ which often runs between 128 kbit/s
