Josephs Story
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?
The cell respiration process is affected due to the loss of oxygen, blood glucose, and waste removal. This happens because glucose starts the process of glycolysis. Oxygen is needed for reactions in the mitochondria, and carbon dioxide needs to be removed from the cells. Carbon Dioxide levels started building up, as well as the bodies PH level. Without the heart pumping the oxygen and blood glucose won’t reach the vital organs of the body that need them for homeostasis. Sooner or later, without the ability to produce ATP, and the leakage of sodium, the body’s cells will die.

C. Which intracellular organelles have membranes as part of their structure? How would the breakdown of the membranes of these structures affect the function of joseph's heart cells? Every intracellular organelle has membranes. Endoplasmic reticulum, Golgi apparatus, mitochondria, and the nucleus are more common intracellular organelles that have membranes. If the mitochondria membrane is damaged it cannot produce ATP. Without ATP some of the channels in the plasma membrane will not function without energy. If the plasma membrane is damaged the channels are not working which would result in poor communication between cells. Pretty much SYSTEM OVERLOAD!!

D. Two important pieces of information- the instructions Joseph's body needs to repair itself and his predisposition for vascular disease- are both contained within the cell on which structures? The predisposition is within the Mitochondrial DNA since he has a family history of vascular disease, it’s already in his genes. The repairer would be in the mRNA which works the synthesis of proteins that fix the body.

E. Joseph's heart attack has caused the function of his cells to change. What types of proteins in the cell membrane were involved in the homeostatic imbalances of his heart cells?
ATP affects the pumping into the membrane by opening channels, when the channels are not working properly the cell doesn't function

Phospholipid Bilayer Membrane of Beetroot (Beta vulgaris) Cells. Introduction Cellular membranes function as a selective barrier that allow the passage of select nutrients, chemicals and waste across their boundaries. The membrane is an extremely thin layer (8 to 10 nm) thick, which is partially permeable (Reece et al. 2011). It is a phospholipid bilayer that consists mostly of lipids and proteins. Phospholipids are essential for cells because they make up cell membranes. The hydrocarbon tails…

Essay on Spectrometry Analysis of Biological Membranes

Spectrometry Analysis of Biological Membranes Measurements of absorbance and color concentrations were taken to observe the affect of three stress factors on biological membranes. The detergents, pH, and concentration gradients in water were experimented on beet membranes. The results observed proved the validity that the factors, if not at the right conditions, cause cell death by disruption of the cellular membrane. Introduction The physical properties of membranes are important to chemical and…

The Skinned Muscle Fibre Is Immersed In The Salt Solution Similar To Intracellular Muscle Cytoplasm

Answer 1 If the skinned muscle fibre is immersed in the salt solution similar to intracellular muscle cytoplasm and also contains Ca2+, the cell membrane of the fibres will become impermeable for small molecules like ATP because the permeability of the cells depend on the concentration of free ionized calcium Ca2+ in cytoplasm. This can be explained with the help of an example. Put the whole muscle fibres in the Ca2+ indicatorfura-2 conjugated to high molecular weight dextran. The fluorescence…

The mutation in the PEX5 also altered the mitochondrial respiratory chain enzymes as the mutants showed an increase of mitochondrial manganese-superoxide dismutase. They hypothesised that this alteration could lead to increased production of…

Adaptive Response Paper

Abstract Adaptive immunity is an important part of the immune system. It is the third line of defense in the human body, which includes highly specialized systemic cells and processes that eliminate or prevent pathogenic growth. Once external barriers have been compromised and inflammation (innate immunity) has been activated, the adaptive response is called into action (Huether & McCance, 2012). It develops slower than the innate inflammatory response and is specific—unlike inflammation, which…
