Whether more or less oxygen is delivered to the systemic cells under the conditions of the lower cellular PO 2 . Concept introduction: When the partial pressure for a specific gas is greater in one region than in another region, a partial pressure gradient exists. If a partial pressure gradient exists between two regions for a particular gas, then the gas moves to the area of lower partial pressure gradient from the area of higher partial pressure gradient. This movement may continue until the partial pressures in both the regions become equal. The respiratory gas exchange in both systematic and alveolar gas exchange is dependent upon the partial pressure gradients.

Summary Introduction

To determine: Whether more or less oxygen is delivered to the systemic cells under the conditions of the lower cellular PO₂.

Concept introduction: When the partial pressure for a specific gas is greater in one region than in another region, a partial pressure gradient exists. If a partial pressure gradient exists between two regions for a particular gas, then the gas moves to the area of lower partial pressure gradient from the area of higher partial pressure gradient. This movement may continue until the partial pressures in both the regions become equal. The respiratory gas exchange in both systematic and alveolar gas exchange is dependent upon the partial pressure gradients.

Summary Introduction

To determine: Whether the oxygen reserve is higher or lower.

Concept introduction: The respiratory system is the biological system that consists of specific organs and structures used for the gas exchange in animals. Gas exchange is the transport of respiratory gases between blood and either alveoli or cells of systemic tissues. During breathing, the gases in air move down collectively the pressure gradient, whereas each gas moves down independently its own partial pressure during gas exchange.

Svp je voulais demander l aide pour mon exercice

Imagine that you are a clinical geneticist. Your colleague is an oncologist who wants your help explaining the basics of genetics to their patient, who will be undergoing genetic testing in the coming weeks for possible acute myeloid leukemia (AML) induced by the radiation she had several years ago for breast cancer. Write a 1,050- to 1,225-word memo to your colleague. Include the following in your memo: An explanation of the molecular structure of DNA and RNA, highlighting both similarities and differences A description of the processes of transcription and translation An explanation of the differences between leading and lagging strands and how the DNA is replicated in each strand Reponses to the following common questions patients might ask about this type of genetic testing and genetic disorder: Does AML run in families? What genes are tested for?

Respond to the following in a minimum of 175 words: What are some potential consequences that could result if the processes of replication, transcription, and translation don’t function correctly? Provide an example of how you might explain these consequences in terms that patients might understand.
