Overview In the cell‚ chemical reactions take place to help release and convert energy. For example‚ sugars are converted to amino acids to make proteins‚ but in digestion‚ proteins are broken down into monomers of amino acid which then are converted into sugars. The process of cellular respiration is an example of chemical reactions. Throughout the chapter‚ the cell’s metabolism will be examined to understand how it controls the chemical reactions that take place in the cell. Section 6.1 -

Experiment IV: Study of Krebs cycle using Mitochondria from Mung Bean Seedlings INTRODUCTION The mitochondria is a very important organelle in the plant cell because it carries out very important cellular reactions in the cell like the Krebs cycle and oxidative phosphorylation which is how the plants produce ATP from the pyruvate produced through glycolysis (Meyer and Millar‚ 2008). Glycolysis produces a net of 2 ATP for the plant which is not enough for the cell to function while the Krebs cycle

The aim of this experiment was to investigate the effect that a glucose concentration has on the rate of fermentation. This was done by adding a variety of different glucose concentration into a test tube‚ siting in a water bath. The carbon dioxide would be collected in the test tube and therefore would measure the rate of fermentation. The results parsley supported the hypothesis that‚ “If the glucose concentration increases‚ the rate of fermentation increases‚ therefore the more carbon dioxide

The fungal plasma membrane proton-ATPase is a membrane protein that belongs to primary ATPase-transporters class. ATPases in this class are characterized by their ability to convert the chemical energy generated by ATP hydrolysis to kinetic energy required for the transport of ions through the membrane. ATPase transporters are classified to P-‚F-‚V-ATPases and ABC transporters. Fungal plasma membrane proton-ATPase belongs to class P-type ATPases . Other members of the P-type ATPase class include

Energy is needed by the body to stay alive‚ grow‚ keep warm and move around. Energy is provided by food and drink. It comes from the fat‚ carbohydrate‚ protein and alcohol the diet contains. Energy requirements vary from one individual to the next‚ depending on factors such as age‚ sex‚ body composition and physical activity level. Energy expenditure is the sum of the basal metabolic rate (the amount of energy expended while at complete rest)‚ the thermic effect of food (TEF‚ the energy required

Photosynthesis Essay During the Light Dependent Reactions‚ activity occurs within the thylakoids of the chloroplast. NADP+ accepts two high energy electrons and an H+ ion and then converts into NADPH. This process ultimately traps some of the sunlight in chemical form. Then‚ NADPH is able to carry the energy it absorbs to the rest of the cell. The reaction produces O2 gas and converts ADP to ATP and NADP+ to NADPH. First‚ pigments in Photosystem II absorb light‚ which is then absorbed by electrons

Describe the role of the citric acid cycle as a central metabolic mechanism. Explain what happens to the cells’ abilities to oxidize acetyl CoA when intermediates of the cycle are drained off for amino acid biosynthesis. Describe the three steps in photosynthesis‚ detailing the interrelationships among them. (c.f. the discussion in the online classroom). For this assignment you don’t need to use other sources besides the information given in the commentary‚ animations‚ and/or textbook. However‚

Mitochondria are one of the most abundant organelles‚ which exercise various essential roles and function to all living things. Often time‚ this tremendous organelle is referred to as the powerhouse of the cell‚ due to their essential function in production of energy. The production of ATP‚ and regulation of intracellular calcium levels is also of great importance in the survival of neurons‚ which are cells in the brain‚ that make part of the Central Nervous System (CNS).
