1. How does meiosis differ from mitosis? What is the ploidy number of the products in both processes? Mitosis is a process of asexual reproduction in which the cell divides in two producing a replica, with an equal number of chromosomes in each resulting diploid cell. It basically creates all cells other than sex cells.… Continue reading Meiosis and Stuff!
This week we learned more about the eukaryotic cell cycle and how cancer forms. Because I wasn’t in class on Thursday when everyone did the cancer lab, I was instructed to write about the biointeractive cell cycle and cancer activity. Big idea 3.A.2 The two types of cell division are mitosis and meiosis. Meiosis is a… Continue reading Eukaryotic Cell Cycle and Cancer
Chloroplasts, found in plant cells and not animal cells, conduct photosynthesis. There main function is absorbing sunlight and converting it into sugar molecules and ATP/NADPH for energy. Here’s a simple diagram of what a chloroplast looks like. The chloroplasts are double membrane bound organelles and have a system of three membranes: the outer membrane, the… Continue reading An Intro to Photosynthesis
Anaerobic cellular respiration vs. aerobic cellular respiration: To my understanding, there are 3 main types of cellular respiration: Anaerobic, Aerobic, and fermentation. Aerobic respiration takes place in the presence of oxygen, and produces the most ATP in the cycle from one molecule of glucose compared to the others. The chemical formula for glucose going through… Continue reading Cellula(r)espiration
This week was mainly focused on the concept of cell signaling and additionally cellular respiration. We first started with a diabetes and insulin packet about cell signaling. Not gonna lie, it was a little cheesy. But it had some good information buried in there. Basically, a cell signaling pathway (3.D.2 and 3.D.3) has four essential… Continue reading Loads o’ Cell Signaling
These past couple weeks have been focused on the basic structure of the cell. Let’s set down the requirements for the cell. All cells have a plasma membrane and a cytosol (the watery part in a cell) The all also have phospholipids, chromosomes in form of DNA, and ribosomes There are two main types of… Continue reading Cells, Cells, And More Cells!
This week we basically just focused on the yeast ball lab and how quickly the yeast was catalyzed. So here’s what happened: Catalase which is found in both plant and animal cells has a very important function in which it prevents the accumulation of toxic levels of H2O2 (a by-product of metabolic processes). An example of… Continue reading Yeast Balls
