Protein Transport into Mitochondria

Protein Transport into Mitochondria

Hello frnds in this videos we will be discussing abt Protein Transport into Mitochondria……….. we know Most of the proteins destined for mitochondria are synthesised in the cytosol and then these proteins are transported into the mitochondria … and for this transport to occur the Proteins contain Signal Sequences , where to get transported in […]

Is Our Food Becoming Less Nutritious?

Is Our Food Becoming Less Nutritious?

Is our food becoming less nutritious? Many people claim that the nutrient content in our food has been decreasing over the decades. But is this really true, and should we be worried? A study published in 2004 looked at 43 different common garden crops, and how their nutritional value had changed between 1950 and 1999. […]

Proteins and Nucleic Acids

Hey folks, this is going to be our second screencast on the big four molecules, and this time we’re going to talk about proteins and nucleic acids. So when we talked about carbohydrates and lipids, we mostly used carbon hydrogen oxygen and nitrogen, but today we’re going to add phosphorus and sulfur into the mix […]

Biomolecules: The Proteins

Biomolecules: The Proteins

Welcome to Biomolecules: The Proteins. Proteins do most of the work in cells including DNA replication, transportation of molecules, and providing structure to cells. They’re also some of the largest biomolecules because they’re made up of long chains of building blocks, called amino acids. Proteins comprise ten to thirty percent of cell mass, and have […]

Proteins and Nucleic Acids : Key Biomolecules II

Hi, everyone! Welcome back to BOGObiology! This tutorial is going to cover proteins and nucleic acids. We will discuss their structure their function and where they can be found. Different groups of atoms combine to form biomolecules. When we talked about carbohydrates and lipids, we used carbon hydrogen oxygen and sometimes nitrogen. Now that we’re […]
