Why Do Bats Carry So Many Dangerous Diseases?

Why Do Bats Carry So Many Dangerous Diseases?

[♪ INTRO] One fifth of all mammal species today are bats. And that’s awesome, because they help us out in all sorts of ways. Like, they pollinate a lot of plants, help regrow forests and control pests, and their poop is pretty excellent fertilizer. Plus, they’re just really cool. Some of them can sense magnetic […]

How mitochondrial diseases are inherited

How mitochondrial diseases are inherited

RL: We’re always accustomed to thinking of inheritance as what happens in terms of the nuclear genome that we inherit from our mother and the nuclear genome that we inherit from our father. But what you will see is that, with mitochondria, the particular complement that is inherited from your mother can be quite different […]

Niacin is neuroprotective in a fly model of Parkinson’s disease

Niacin is neuroprotective in a fly model of Parkinson’s disease

People with certain forms of early-onset Parkinson’s disease may benefit from boosting the amount of niacin in their diet. That’s the upshot of a new study from the MRC toxicology unit at the University of Leicester, which studied fruit flies with a mutation that mimics the human disease. Niacin, or vitamin B3, is found in […]

Introduction to mitochondrial disease

Introduction to mitochondrial disease

RL: We know that mitochondria may indeed be endosymbiotes in the sense that millions of years ago, these tiny bacteria were engulfed by larger cells and ultimately evolved to be co-dependent with our cells. We provide them with foodstuffs and protection from predation, and in turn, they provide us with the majority of the ATP […]

Mitochondrial diseases

Mitochondrial diseases

Mitochondrial diseases cover a wide range of conditions caused by genetic mutations. In the UK alone, they affect thousands. Mitochondria are the ‘powerhouses’ of the cell. They use a process called ‘oxidative phosphorylation’ to generate energy. But a mitochondrion is a complex piece of machinery, and a lot can go wrong. It takes around 1500 […]

Photosynthesis vs. Cellular Respiration Comparison

Photosynthesis vs. Cellular Respiration Comparison

Hey, folks! Welcome back to BOGO biology! This week we’re going to explore energy transformation by comparing the processes of photosynthesis and cellular respiration. Here’s what the AP bio curriculum has to say on the subject. They want you to know that, quote, “biological systems utilize free energy and molecular building blocks to grow to […]

What Is Aerobic Respiration? | Physiology | Biology | FuseSchool

Respiration is just breathing right? Wrong! Respiration is the chemical process that supplies the body with energy for all other life processes. Growth and repair of cells, muscle contraction, protein synthesis, sending nerve impulses, absorbing molecules and active transport to name just a few. It happens in all living cells. Not just animal cells but […]

Cellular Respiration Part 1: Glycolysis

Cellular Respiration Part 1: Glycolysis

Hey it’s professor Dave, let’s talk about glycolysis. We need energy to do literally anything, from running a race, to simply breathing. And every cell in your body is furiously producing all this energy all the time. Where does this energy come from? Well technically it arrives from the sun. The sun is releasing enormous […]
