Photosynthesis and cellular respiration Introduction: Photosynthesis is the process which used by plants to capture light energy and use it to do chemical reactions that change carbon dioxide and water into oxygen and energy (ATP)‚ carbohydrates just like sugar. Cellular respiration is the process that releases energy by breaking down glucose and other food with oxygen. Plants cells do photosynthesis and cellular respiration both ‚but animal cells can only do the cellular respiration. In photosynthesis reaction

Muscle dysmorphia is a body dysmorphic disorder whereby sufferers are obsessed with increasing their “muscularity and leanness”‚ even if they may already be very muscular compared to the average person (Choi‚ Pope‚ & Olivardia‚ 2002; Pope‚ Gruber‚ Choi‚ Olivardia‚ & Phillips‚ 1997). They strive to make up for their overstated physical weakness through many hours of weight training and a disproportionately large focus on nutrition (Mosley‚ 2009). They are resistant to persuasion to think better of

Cellular Respiration Photosynthesis Organelles Mitochondria Chloroplast Organelle Structures The double-membraned mitochondrion can be loosely described as a large wrinkled bag packed inside of a smaller‚ unwrinkled bag. The two membranes create distinct compartments within the organelle‚ and are themselves very different in structure and in function. Two membranes contain and protect the inner parts of the chloroplast. The stroma is an area inside of the chloroplast where reactions occur and starches

BIO 101 Lecture Notes for Respiration‚ Fermentation‚ and Photosynthesis Respiration During aerobic respiration‚ glucose is completely oxidized (all H’s removed) leaving CO2 as an endproduct. The H’s are taken by coenzymes (NAD and FAD) to the electron transport chain. There the energy is drained from the hydrogen electrons and the energy is used to make ATP. The H’s are ultimately accepted by O2 to make H2O as an endproduct. Respiration occurs in three major stages: 1) Glycolysis

energy production. They are also the responsible location for which respiration takes place. Mitochondria contain enzymes that help convert food material into adenosine triphosphate (ATP)‚ which can be used directly by the cell as an energy source. Mitochondria tend to be concentrated near cellular structures that require large inputs of energy‚ such as the flagellum. The role of the mitochondria is very important in respiration. In the presence of oxygen‚ pyruvate or fatty acids‚ can be further

Muscle Cell at rest: As the muscle cell is at rest it has a resting potential of -90mV. The K+ is all located inside the cell‚ the Na+ is located outside of the cell and the Ca2+ is located inside the sarcoplasmic reticulum. All leak channels and pumps are closed at this point. Muscle Cell stimulated by Acetylcholine: A motor neuron releases Acetylcholine which diffuses toward the muscle cell across the neuromuscular junction. As the Acetylcholine binds to a receptor on the muscle

Muscles of mastication are known to be the most crucial muscles in the head aside from the muscles that are required to show facial expressions. The four muscles of mastication include: • Masseter muscle • Temporalis muscle • Medial pterygoid muscle • Lateral pterygoid muscle Each of which has a

exercise. Although stretching doesn’t reduce bodily fat nor does it gain muscle; it does set a good foundation for you to perform the necessary activities that lead to good health. With proper flexibility‚ many functions that were previously not achievable can now be done. For instance‚ a tennis game can be fun for a little while. But as your muscle tense up‚ you risk probable sourness and cramping. With good flexibility‚ your muscles stay loose and relaxed and your attitude toward the tennis game and
