Cellular signaling has been a highly studied topic in biological and medical areas‚ being essential for many cellular processes. The efforts toward the comprehension of signaling pathways may help to understand a large range of molecular mechanisms such as those involved in host parasite interaction or in many types of cancer (Hanahan and Weinberg 2011). Cellular signaling is driven mainly by protein phosphorylation and dephosphorylation events‚ controlled by protein kinases and protein phosphatases

Cellular respiration is a series of metabolic processes by which living cells produce energy through the oxidation of organic substances. Photosynthesis is the process by which green plants and some other organisms use sunlight to make foods from carbon dioxide and water. A critical cycle of energy and matter that supports the continued existence of life on earth are formed by cellular respiration and photosynthesis. When it comes to the stages of cellular respiration‚ there are three stages. The

ABSTRACT The effect of co-factor (MgSO₄) and the nature of substrate on the rate of cellular respiration in yeast were determined using two different set-ups. In the first set-up‚ two test tubes were used where one contains 7m and the other with 7 mL 0.2M MgSO₄ and both containing 7mL 10% yeast suspension. Here‚ data shows that the H₂O mixture showed higher amount of CO₂ evolved than MgSO₄. In the second set-up‚ six Smith fermentation tubes were used each containing different 15mL solution (starch

B- Assuming Joseph’s heart has stopped‚ what cellular processes and membrane functions are going to be affected by the loss of oxygen‚ blood glucose‚ and waste removal? Since Joseph’s heart has stopped oxygen‚ glucose‚ and other essential ions that were required for the heart to pump slowed‚ but the cells continued working using the supply of ATP rapidly. The Carbon dioxide levels inside of the cell rose‚ and the pH began to drop. The mitochondria no longer had the required oxygen and glucose

Photosynthesis and Respiration Objectives: In this activity we will review the process of photosynthesis and cellular respiration‚ and become familiar with the use of a pH indicator for investigating these processes. Following this activity your group will generate a new research question about photosynthesis or respiration‚ and utilize the pH indicator system for the experiment that your group will design‚ implement and interpret. Introduction: Photosynthesis is the process by which plants and

Cellular respiration: one of the most significant processes known to life today. Cellular respiration is indeed a lengthy process‚ especially just to make ATP (energy)‚ and it all starts with a glucose. The first process to cellular respiration is glycolysis‚ which can be literally translated to the breaking of glucose. To note‚ glycolysis takes place in the cytoplasm of the cell. There are two parts to glycolysis: the “investment” phase and the “harvest” phase. With the aid of two ATP‚ the first

if the rate of cellular respiration will be affected if we change the food source from glucose to three different experimental variables (fructose‚ sucrose‚ lactose). Cellular Respiration is a process that generates ATP and it involves the complete breakdown of glucose to carbon dioxide and water. Carbohydrates‚ fats‚ and proteins can all be used as fuels in cellular respiration‚ but glucose is most commonly used as an example to examine the reactions and pathways involved. Cellular Respiration can
