just like other organisms‚ they must respire in order to survive. Respiration can be defined as the controlled release of energy from organic compounds to form adenosine triphosphate (ATP). The type of respiration that occurs is called aerobic respiration. It occurs when glucose and oxygen are present. It can be summarized by the equation: . Enzymes play a very significant part in respiration. During the different stages of respiration‚ enzymes that are often found in the matrix of the mitochondria

What is Life? This perennial question the answer to which has somehow eluded the most brilliant minds. For while scientists have identified many years ago the right mix of the atoms and molecules that constitute cellular material‚ they have not succeeded in ‘switching it on’ to make it alive‚ or ‘breathing life’ into it (Rabago et.al‚2006) In this module you will: a. Explain the concepts of the cell theory b. Identify the parts of a cell c. Describe the function of each cell part d. Differentiate

goes beyond photosynthesis. The sensing of light is as important for plants as vision for animals. Light receptors in plant cells convert light into chemical signals that bring about important stages in the plant’s life cycle‚ from the germination of seeds to the production of flowers. However‚ light is essential to plant reproduction and growth‚ too much sunlight can be harmful. Sunlight can overheat a plant or overload its photosynthetic machinery.

In addition‚ the predisposition to use is a necessary but not sufficient explanation of use. Use also presupposes the availability or supply of‚ or opportu- nity to take‚ a given drug.

When plants want to reproduce the plants make seeds that can be dispersed by air‚ water‚ or animals and the seeds that survive find a place in the ground to start grow. For some plants‚ the seeds are in protective shelling like fruits and pinecones. This extra protection layer is there to allow the seeds to make it new ground by animals

ANATOMY AND PHYSIOLOGY AN INTRODUCTION TO RESPIRATION In this essay we will consider a few major aspects of respiration. We shall first consider the interesting history of the study of respiration before moving on to our modern understanding of respiration. We will look at the structure and function of the respiratory system including the upper and lower respiratory tracts with a note on the control system. Secondly we will consider the physiology of respiration. Thirdly we will discuss some of the major
