What Affects The Rate Of Respiration In Yeast

Consumers will consume oxygen and these will take the oxygen from the lake. This in turn will cause the dissolved oxygen level.

Aquatic environments require different methods for adaptation. The pressure in water increases as depth increases and aquatic organisms have to deal with it. Mobility of small animals versus larger ones help the ones with greater SA:V flow or be moved by currents, which is a disadvantage for bigger animals that have to constantly move. Light limitations also affect living things in water, mostly plants because they have to photosynthesize to grow, and the attenuation of light increases in depth, they have to take advantage of other resources to get the light they need and the nutrients to survive. Salt tolerance is vital; the process of osmosis moves water from high concentration of solutes to low concentration of solutes, if an organism doesn’t have enough salt contents starts losing water and dehydrates

Cellular respiration is a redox reaction that combines glucose & oxygen to produce carbon dioxide, water, and energy.

Combustion vs Respiration Activity 1 - Answer the following question in relation to combustion Explain what a combustion reaction is. Combustion usually occurs when a hydrocarbon reacts with oxygen to produce carbon dioxide and water. Write the general word equation for combustion. In words, the equation for combustion, in most cases, is a hydrocarbon plus oxygen equals carbon dioxide plus water plus heat.

2. If the ppm of dissolved oxygen is increased in water then there will be more fish observed.

Oxygen is used for cell respiration which is created and found in the mitochondria. The mitochondria need oxygen to make glucose for the body cells and to create carbon dioxide. Glucose is used in the liver to regulate the body’s sugar levels. Carbon dioxide is then added to water and then to energy for cell respiration and for the body systems and organs to be able to work.

Photosynthesis is essential to all living organism such as animals and plants. Photosynthesis is a process used by plants and other autotrophs to capture light energy and use it to power chemical reaction that converts carbon dioxide and water into oxygen, carbohydrates and water. (Textbook: Principles of Biology). The reactants and the products of photosynthesis are:

The range is between 0 and 14 and shows how basic or acidic the tested water is on a logarithmic scale. The lower the number, the more acidic the water is. A healthy lake is slightly acidic at 6.5 and in levels lower than 4.2, fish will not be able to survive. As pH levels move away from 6.5, more stress could be caused to aquatic life which could raise mortality rates. Changes in pH levels can also be natural or anthropogenic. Natural influences include carbonic materials in the water. When carbonic minerals are in the water, the alkalinity of the water increases (Host 2005). The levels of pH can also fluctuate due to human-induced reasons such as pollution and acid rain. Acid rain is any form of precipitation that has a pH level less than five (Mack 2014). Point source pollution can also influence pH levels. Chemicals from point source pollution result from agriculture and industrial runoff. Decreases in pH levels could result from respiration, decomposition, and an increase in carbon dioxide. Increases in pH levels result from photosynthesis and a decrease in carbon

All living things need to respire in order to survive, this is necessary for energy and this is called Gas exchange. This is the exchange of different gases oxygen (O₂) and carbon dioxide (CO₂). During respiration oxygen is diffused into the cells of the organism and carbon dioxide is the waste product. However there is a form of respiration called anaerobic respiration where the oxygen is not used but the waste product is still carbon dioxide. If respiration did not occur the blood would not be oxygenated therefore energy wouldn't be able to change the state of the cells to enable life processes.

All things need energy to grow. We get energy from the food we eat. Plants get energy from light through a process called photosynthesis. This is how light affects the growth of a plant. Without light, a plant would not be able to produce the energy it needs to grow (Rhoades, 2008). Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product. The rate of photosynthesis is affected by the different wavelengths of light a plant is exposed to because different pigments in chloroplasts absorbs different wavelengths for use in photosynthesis (Terms, 2017).

This is when the water molecules come from a higher concentration within the body and they then transfer into a region of low concentration, this happens through the partially permeable membranes within the

All living organisms respire. In order for organisms to reproduce and survive, the cells need to use the energy that is required to form the life processes, e.g (they need to carry out MRSGREN). Gas exchange is the delivery of oxygen from the lungs to the blood stream and the elimination of carbon dioxide from the blood stream to the lungs. It takes place in the lungs between the alveoli and a network of tiny blood vessels called capillaries.

Every living thing needs cellular respiration to survive. Cellular respiration is the process that releases energy by breaking down glucose and other food molecules in the presence of oxygen. This process happens through three distinct operations which are glycolysis, the Krebs cycle, and the electron transport chain. Throughout these cycles, our bodies turn oxygen and glucose into carbon dioxide, water, and energy. Although this system seems simple enough, cellular respiration can not take place in just one step because all of the energy from glucose would be released at once, most of it being lost in the form of light and heat. All this plays a very important role in our lives and without it, organisms would cease to exist.

Another crucial component is the description of the characteristics of a lake is to monitor the quantity of oxygen and carbon dioxide to various depths. There is a reciprocal relation that exists between these two elements when they are compared to the depth of a lake (Figure 2) (Korstad 2017). A lake has the capacity top adhere oxygen by absorption or photosynthesis. The levels high oxygen is necessary to maintain the necessary nutrients inside the water, and at the same time providing a source food to all fishes. It is common to see
