In the process of cellular respiration‚ there are three main parts; Glycolysis‚ Krebs Cycle‚ and Electron Transport Chain. All three of these processes form together to make cellular respiration happen‚ and that gives our bodies energy to do the work that we need to perform every single day. Without cellular respiration‚ our bodies would not have enough energy to perform everyday tasks‚ let alone live and survive. The first process‚ glycolysis‚ starts with a few molecules of glucose. There are

All Public Transport in Our Cities Should Be Free In most cities‚ public transport is partially subsidized by the city council‚ which means that bus and underground fares are usually reasonably low. However‚ some people argue that fares should be abolished altogether . In this essay‚ I intend to examine the arguments for and against free public transport. One of the strongest arguments in favour of free public transport is that it would encourage more people to use the buses and tubes

Active transport and Passive transport are biological functions that carry water‚ nutrients‚ and oxygen into cells and for the removal of waste in the cell. Active transport utilizes chemical energy to move substances from lower concentrations to higher concentrations. Whereas Passive transport moves substances from areas of high concentration to areas of low concentration‚ and it does not need to use energy. Active transport uses a chemical called ATP as its energy source in its functions. Without

PEOPLE ENTERING THE CITY SHOULD USE PUBLIC TRANSPORT 1. INTRODUCTION Public transport also known as public transit or mass transit is a shared passenger transportation service which is available for use by the general public. Public transport include buses‚ trains‚ ’rapid transit’ like commuter and ferries. Other than that‚ it also includes taxicab and car pooling which are not shared by strangers without private arrangement. Most public transport runs to a scheduled timetable with the most

Discuss the structure of the plasma membrane and explain the process of active and passive transport through the membrane. The plasma membrane is made up of proteins that form pores and channels‚ carbohydrate molecules that are used for cell recognition and cholesterol to provide membrane stability. Phospholipid molecules are the most abundant component found in the plasma membrane. Phospholipids molecules are composed of a phosphate head and a lipid tail; the structure of a cell membrane

into a category called active transport‚ while the ways that don’t require energy are put into a category called passive transport. An example of active transport is the proton pump. The proton pump is an integral part of chemiosmosis‚ and it pumps protons from an area of low concentration to an area of high concentration. This requires energy since things like to move from an area of high concentration to an area of low concentration. An example of passive transport is facilitated diffusion. This
