Biology 1101 – Homework 3 Cells: Structures & Processes Organelles & Illness - Imagine that you are part of a research team that specializes in diagnosing disorders associated with malfunctioning cellular organelles and structures. Medical doctors consult you to provide a cellular explanation for particularly difficult cases. You recently received the two patient histories outlined below – what is your diagnosis? Note – this exercise is only asking you to determine which cell structure might be

The human body is a remarkable species‚ capable of doing some of the most amazing things known to man. It requires a lot of energy and the organisms that make it up constantly have a task to perform. One of the most important functions in the human body is called cellular respiration. It is defined as a process in which cells take the food humans ingest and turn it into energy that can be used by the body in the form of ATP‚ also known as‚ adenosine triphosphate. The creation and distribution of
Premium Adenosine triphosphate Metabolism Cellular respiration
Cellular respiration a process in which sugar and oxygen are used to produce adenosine triphosphate (ATP)‚ water‚ and carbon dioxide. The chemical equation for this reaction is C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy (ATP). Cellular respiration occurs in 4 steps: Glycolysis‚ the preparatory reaction‚ the Krebs Cycle‚ and the oxidative phosphorylation. Glycolysis occurs in the cytoplasm of the cell‚ in this process glucose is broken into two 3 Carbon molecules called pyruvates. The preparatory reaction

12. Briefly discuss the role of the electron transport chain in cellular respiration. In your explanation‚ discuss and identify key molecules involved in this process and explain their relationship which each other in terms of how they contribute to the main cellular purpose of this process. Electron transport chain plays a key role of in the production of oxygen in cellular respiration. ETC uses many enzymes located on the inner mitochondrial membrane during the production of oxygen. The source

A1. Role of Enzymes in Processes Enzymes are organic catalysts that help to speed up the breakdown of a molecule‚ such as fructose. The enzyme helps a chemical reaction take place quickly so that the reaction happens properly. In order for that to happen the enzymes process by the lock and key model‚ the lock is the substrate and the enzyme is the key. The active sites are specific to a certain substrate of a molecule‚ so the enzymes only have one job to do. The shape of an enzyme is not changed

As biologists probed deeper into the microcosm of cells‚ they found an entire autonomous biological system‚ with many organelles which served various functions. The trio consisting of Keith R Porter‚ Ernest F Fullam and Albert Claude discovered the endoplasmic reticulum and published their research paper regarding it‚ in 1945. It was a very important discovery‚ as this cell organelle plays a major role in the functioning of every eukaryotic cell. Let us take a look at the structure of endoplasmic
