1. Explain why the following statement is incorrect. Plants perform photosynthesis, but only animals perform cellular respiration.
It is true that plants perform photosynthesis. What it is not true, it is that only animals perform cellular respiration. Cellular respiration is the process in which an organism obtains its energy. All living organisms perform cellular respiration, whether they are plants or animals. For instance, every cell in an animal requires oxygen to perform cellular respiration which gives off carbon dioxide and water as waste products. Respiration is the process by which animals exchange these gases with their environment. Animals have specialized systems of structures that help them to do this successfully and efficiently.
Consider cellular respiration. Explain what happens to the carbon atoms found in the glucose molecule throughout cellular respiration, to the very end of the process.
The carbon atoms are released as carbon dioxide (C02) which is what humans breathe out. Cellular respiration is the process of oxidizing food molecules, like glucose, to carbon dioxide and water. The energy released is trapped in the form of ATP for use by all the energy-consuming activities of the cell. The process occurs in two phases: glycolysis, the breakdown of glucose to pyruvic acid. The complete oxidation of pyruvic acid to carbon dioxide and water (“Cellular Respiration,” 2015).
3. Metabolism is the total of all the chemical reactions that take place in a living organism. Explain how three different groups of foods are used in cellular
As the work of the muscle increases, more and more ATP gets consumed and must be replaced in order for the muscle to keep moving. Because ATP is so important, the body has several different systems to create ATP. These systems work together in phases. The interesting thing is that different forms of exercise use different systems, so a sprinter is getting ATP in a completely different way from a marathon runner. ATP comes from three different biochemical systems in the muscle, in this order: phosphagen system, glycogen-lactic acid system, and aerobic

    The data collected during this experiment has shown that a relationship likely exists between the rate of muscle fatigue and the time spent performing vigorous exercise prior to the set of repetitive movements. This is likely due to a build-up of lactic acid and lactate as a result of anaerobic respiration occurring to provide energy for the muscle cell’s movement. As the pH of the cell would have been lowered, the enzymes necessary in the reactions would likely not be working in their optimum pH range, slowing the respiration reactions and providing an explanation to why the average number of repetitions decreased as the prior amount of exercise increased.

    The ATP is used for many cell functions including transport work moving substances across cell membranes. It is also used for mechanical work, supplying the energy needed for muscle contraction. It supplies energy not only to heart muscle (for blood circulation) and skeletal muscle (such as for gross body movement), but also to the chromosomes and flagella to enable them to carry out their many functions. A major role of ATP is in chemical work, supplying the needed energy to synthesize the multi-thousands of types of macromolecules that the cell needs to exist. ATP is also used as an on-off switch both to control chemical reactions and to send messages.

ATP molecules are yield during cellular respiration.

    Animal metabolism consists of the utilization of nutrients absorbed from the digestive tract and their catabolism as fuel for energy or their conversion into substances of the body. Metabolism is a continuous process because the molecules and even most cells of the body have brief lifetimes and are constantly replaced, while tissue as a whole maintains its characteristic structure. This constant rebuilding process without a net change in the amount of a cell constituent is known as dynamic equilibrium (Grolier1996). In the combustion of food, oxygen is used and carbon dioxide is given off. The rate of oxygen consumption indicates the energy expenditure of an organism, or its metabolic rate (Grolier1996).

    Do you know how you are able to run long distances or lift heavy things? One of the reasons is cellular respiration. Cellular respiration is how your body breaks down the food you’ve eaten into adenosine triphosphate also known as ATP. ATP is the bodies energy its in every cell in the human body. We don’t always need cellular respiration so it is sometimes anaerobic. For example, when we are sleeping or just watching television. When you are doing activities that are intense like lifting weights or running, your cellular respiration becomes aerobic which means you are also using more ATP. Cellular respiration is important in modern science because if we did not know about it, we wouldn’t know how we are able to make ATP when we are doing simple task like that are aerobic or anaerobic.

  • Aerobic Respiration

    956 Words  | 2 Pages

    Cellular respiration is an important function for the body to obtain energy (Citovsky, Lecture 18). There are two types of cellular respiration; aerobic conditions and anaerobic conditions. Aerobic conditions are the cellular respiration occurred with oxygen while anaerobic conditions are cellular respiration occurred without oxygen. The most common cellular respiration is aerobic conditions where oxygen were supplied for phosphorylation (Campbell et al., pg 177). In human body, anaerobic conditions occurred when muscle cells are overworked and oxygen is depleted before it could be replenished (Citovsky, Lecture 19). This is a common phenomenon during exercise. The accumulation and production of lactic acid from anaerobic cellular respiration has been always a cause of muscle sore from intense exercise (Campbell et al., pg. 179).

    When humans consume plants, the carbohydrates, lipids, and proteins that are broken down through two forms of cellular respiration. The two processes of cellular respiration displayed in humans are anaerobic or aerobic. The deciding process used depends on the presence of oxygen. Cellular respiration converts the material into useable energy called ATP. ATP is the energy form that cells can use to perform their various functions and it can also be stored for later use. Without plants, none of this energy could be produced and the herbivores that humans consume would not exist.

    Photosynthesis and cellular respiration help sustain life on planet earth as both are metabolic processes in their own way. Photosynthesis is the process by which plants and other organisms use energy from the sun to form glucose from water and carbon dioxide. From there, glucose is then converted to ATP by way of cellular respiration. To convert nutrients that are biochemical energy into ATP, a process such as cellular respiration that has reactions needs to take shape in the cell of an organism, releasing waste products at the same time. For the continuous energy cycle that tolerates life on Earth as we know it Photosynthesis and Cellular respiration very essential. They have a few stages where energy and various connections occur within the eukaryotic cell. Cellular respiration takes place in the lysosome, an organelle that is found in the cytoplasm of eukaryotic cells. It uses enzymes to break down biomolecules including proteins, nucleic acids, carbohydrates, and lipids. Photosynthesis involves the chloroplasts, which contain pigments that absorb the sunlight and then transfigure them to sugars the plant can use. Those specific processes are crucial in how far and diversified evolution has

    Photosynthesis is the process in which living cells from plants and other organisms use sunlight to produce nutrients from carbon dioxide and water, the image below “Diagram of photosynthesis 1,” helps show this process. Photosynthesise generally creates oxygen as a by-product through the use of the green pigment, chlorophyll, found in the plant that helps this reaction occur. “Photosynthesis provides us with most of the oxygen we need in order to breathe. We, in turn, exhale the carbon dioxide needed by plants,” (factmonster,2017). This is able to show us why photosynthesis is so greatly needed to occur through plants in order to give one another essentials needed for continuity of life. “Plants perform photosynthesis because it generates the food and energy they need for growth and cellular respiration,” (photosynthesieeducation, 2016).
