Some of the things that will be discussed are how photosynthesis and respiration are linked in order to provide you with energy from the food we eat. The absence of oxygen some cells and organisms can use glycolysis coupled to fermentation to produce energy to your cells. Cells use enzymes as biological catalysts to increase or accelerate the rate of reactions.

Energy, Metabolism, and Cells

The third one is vascular bundle ( which are the veins) and the mesophyll. There is no occurrence of photosynthesis in the upper and lower epidermal cells therefore they do not have chloroplast; their simply there to guard the rest of the leaf. The stomata allow gases like 〖CO〗_2(Carbon Dioxide) in and discharge O_2(oxygen); this happens generally in the sub epidermis. The veins of the leaf (vascular bundle) move nourishments and water through the plant as required. A mesophyll cell, which can be found in between the epidermises, contains chloroplasts: photosynthesis takes place here, according to ( 2000).
Aerobic Respiration is the process where oxygen takes part in the breaking down of molecules then releasing electrons forming energy. Adenosine Triphosphate (AT) which is liable for storing and carrying out energy to additional cells is a substance created by aerobic respiration. The nourishment that animals eat eventually is broken down to its most basic form that is sugar according to (Black, K. 2003-2013). There are three main stages of Aerobic Respiration.; Glycolysis, Kreb’s Cycle, and Electron Transport Phosphorylation, according to (Blake K. 2003-2013).
B. Photosynthesis and Respiration are connected between plants and animals through two organisms called autotrophs and heterotrophs. An organism competent of manufacturing its own food is identified as an autotroph. Autotrophs are very much a part of the photosynthesis procedure. Animals and humans that create their own food are considered heterotrophy organisms. Heterotrophs are not part of the photosynthesis process but the organism is an important element of respiration. Since photosynthesis and respiration in one way or another deals with carbon dioxide as well as the reactant water that is how their linked according to (Jansen, J. 1999-2013).
C. Energy is transmitted from sunlight to ATP to sugars and finally to human cells all through photosynthesis. A sequence of reactions in biochemistry where carbohydrates are broken down to a chemical compound called pyruvate; discharging available energy in the form of adenosine triphosphate (ATP) is known as glycolysis, according to (Noiva, Robert. 2004). When energy is extracted from carbohydrates by organisms while there is no oxygen present is Fermentation, according to ( 2008). Fermentation is generally used in many ways.
2. In the absence of oxygen some cells and organisms can use glycolysis coupled to fermentation to produce energy from the sugar created by photosynthesis.
A. A number of organisms in the nonexistence of oxygen from time to time go through a course of action described as fermentation. Fermentation permits these organisms to create energy under anaerobic conditions according to ( 2008).
B. In a biological system energy comes into as light or photons. Through cellular methods including photosynthesis and respiration it is converted into chemical...

In most organisms the primary function of the enzyme is ATP synthesis from adenosine diphosphate (ADP) and inorganic phosphate. The energy needed for this process comes from the proton electrochemical potential difference generated by respiration or photosynthesis. (Boris A.

In addition, it is important to note that photosynthesis is made up of two separate reactions. The first is “light” reactions, which were discussed above, and also “dark” reactions (Calvin Cycle). “Dark” reactions are light independent, which means they can happen during either sunlight or at night. The Calvin Cycle (“dark” reactions) uses the energy

Photoautotrophs transform carbon dioxide to oxygen when photosynthesizing. This is essential for life because oxygen is an important element for respiration which is performed by both autotrophs and animals. Photosynthesis can ne summarized as the following formula: Source: 1. http
