define aging as time dependent or age progressive reduction in intrinsic physiological function leading to a high specific mortality rate and a decrease in specific reproductive rate. Cellular aging therefore‚ can be described as an increased susceptibility to cell death caused by the loss of cellular functions such as cell division‚ cell communication‚ transport and delivery. A cell ages gradually until it gets to the senescence stage which is a process by which a

transport oxygen rich blood from the alveoli back to the heart. Inspiration (the process of inhaling) begins as the external intercostals and diaphragm contract. When this happens‚ the lungs expand. After this‚ negative pressure is used to facilitate respiration. So‚ air moves from an area of higher pressure‚ which is the air‚ to an area of lower pressure in the lungs and aveoli. During inspiration the diaphragm and intercostal muscles contract. The diaphragm moves downwards‚ while the intercostal muscles

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

Cyanobacteria’s big advantage over other early life forms was their ability to perform photosynthesis. They contain a blue photo reactive pigment that can absorb the energy from the sunlight and use it to produce nutrients for the cell. During this process‚ water molecules are broken down into oxygen and hydrogen atoms which are then released in the air. In the very early days of life‚ Earth was populated only by anaerobic bacteria that didn’t need oxygen to survive. When cyanobacteria first made

The effect of different temperature on the cell respiration. Introduction： Cell respiration is the controlled release of energy from organic compounds in cells to form ATP‚and then release waste products. The process of cell respiration can take place in the presence or absence of oxygen. In either case‚the first stage of cell respiration is glycolysis.The effect of temperature on cell respiration mainly depends on the effect of temperature on of enzyme activity.Generally speaking in a certain

Cellular Respiration Photosynthesis Organelles Mitochondria Chloroplast Organelle Structures The double-membraned mitochondrion can be loosely described as a large wrinkled bag packed inside of a smaller‚ unwrinkled bag. The two membranes create distinct compartments within the organelle‚ and are themselves very different in structure and in function. Two membranes contain and protect the inner parts of the chloroplast. The stroma is an area inside of the chloroplast where reactions occur and starches
