As humans, we walk, talk, run, and do an endless list of tasks a day, all of which require energy. Where is all of this power generated from? In this podcast, we will be discussing the structure of a mitochondrion, the function of a mitochondrion, and how cellular respiration takes place within the mitochondrion. 

The Earth formed around 4.5 billion years ago. Over the past billions of years, evolution has greatly changed life as we see it today. If we transport ourselves back in time and look at cells, we will notice that they are extremely simple. But, in the present day, we notice that cells have become much more complicated beings with very complex processes that require many entities in order to function. The process of how this occurred is known as the endosymbiotic theory. This podcast will discuss what the endosymbiotic theory is and the evidence that supports it. 

Mendelian principles have served as a gateway into the functions of how our genetic information is passed on. Over time, we have discovered principles beyond mendelian genetics. In this episode, we review multiple alleles, incomplete dominance, and codominance. We discuss how they function and the examples of each form on inheritance.

In the 1860s, famous scientist Gregor Mendel explored the laws that governed genetics and devised the Law of Segregation. This law is crucial to our understanding of genetics today. In this episode, we dive into the details of how Mendel made this revolutionary discovery and go into depth on the Law of Segregation. 

In this podcast, a major organelle of the Endomembrane system is discussed, the Endoplasmic Reticulum. The episode opens with a discussion on the ER as a whole and then goes into detail on the structure and function of the ER's two counterparts, the smooth and rough ER.  If you have any questions, feel free to send them to https://anchor.fm/christopher-jang/message or https://2255christopher.wixsite.com/biotime/questions

Cell cycle regulation helps our cells control when they want to divide and when they do not. In this episode, we dive into cyclins, cyclin-dependant kinases, mautration-promoting factors, platelet-derived growth factors, and p53. 

With countless organisms roaming the Earth, it is important to have a system to classify them all. The 3-Domain Classification System is a way to sort organisms into 3 categories: bacteria, archaea, and eukarya. In this episode, we explore each of these classfications and the criteria each requires. 

Community Ecology is the discussion of all of the interactions between organisms in a community. Today, we will be going into depth on the 5 categories of community ecology: competition, predation, herbivory, symbiosis, and facilitation. 

Water is essential to life on Earth. Without it, no life as we know it would exist today. Water has many essential properties that allow for it to sustain life on this Earth and this podcast goes into detail on the 5 major properties: high specific heat, high heat of vaporization, universal solvent, strong cohesion tension, and ice is less dense than water. We will also be discussing atomic structure and types of bonds in order to better understand the properties of water. 

One of the basic components that support life are macromolecules with the four being carbohydrates, lipids, proteins, and nucleic acids. This podcast dives into the structure, function, and application of all of these macromolecules. In addition, we will also be discussing dehydration synthesis, hydrolysis, monomers, and polymers in order to have essential background information to understand macromolecules. 

Every living organism you have ever seen has been the result of evolution. If we were to look back on humans millions of years ago, we would have looked drastically different compared to how we look today. In this episode, we discuss the five main factors that contribute to evolution: Genetic drift, gene flow, mutations, non-random mating, and natural selection. We explore the effects each factor and examples of how they allow a population to undergo evolution. 

Cells live in an ever-changing environment, always needing to be aware of their surroundings and reacting to an organism's needs. In order to understand when to take action, cells must receive a message from the outside world in a process called reception. Reception is the first of three steps in cell signaling. In this episode, we review how signaling molecules bind to receptors inside and outside of the cell, along with covering specific cell surface receptors like the G protein-coupled receptors, tyrosine kinases, and ion channel receptors.  If you have any questions, feel free to send them to https://anchor.fm/christopher-jang/message or https://2255christopher.wixsite.com/biotime/questions
