Mitochondria

Figure 1. Detection of the movement of a single mitochondrion with the LKMTA. A. Panels from a time-lapse movie where a single fast transported mitochondrion were digitally removed in Photoshop. The original movie is labeled as the control and the arrows indicate the position of the moving mitochondrion; bar = 10 μM. B. The x and y velocity maps of the control and Photoshopped movies; a cluster of bright pixels in the control x velocity map indicates rightward motion. C. The absolute velocity maps

coupling efficiency in mitochondria and increased superoxide radical generation damaging both nuclear DNA and mitochondrial DNA leading to activation of poly ADP ribose polymerase enzyme (PARP) (Fernyhough et al.Brownlee, 2001; Nishikawa et al., 2000b, to be added). PARP activation leads to inactivation of AMPK which facilitates mitochondrial biogenesis. Thus, PARP activation compromises the cellular mitochondrial genesis which leads to accumulation of damaged mitochondria in the cell. Molecular

bloodstream. There, I get converted into an unstable chemical compound called hemoglobin. I get carried to the cells and broken down. Then I get converted back into oxygen and pass through the cell membrane through diffusion. I then travel to the mitochondria and diffuse into the organelle’s membrane. Before this occurs, 1 processes in cellular respiration already happened

While water is commonly referred to as the “elixir of life” because of its universal qualities, cells are credited as being responsible for making the human organism “alive”. It is the difference between a cluster of organic atoms or molecules that can react chemically, and a single living cell, the smallest unit of life. The study of cells is called cytology, and any research usually requires the use of a high-definition microscope, as most cells in the human body are between 1 micrometer (μm)

Muscle Tissue Introduction * Motion * Results from alternating contraction (shortening) and relaxation of muscles * Skeletal system * Provides leverage and a supportive framework for this movement * Myology – study of muscles Muscle Tissue * Alternating contraction and relaxation of cells * Chemical energy changed into mechanical energy Types of Muscle Tissue * Skeletal muscle – primarily attached to bones * Striated and voluntary * Cardiac

Our skeletal muscle is what generates all of our force to create strength and allow us to move. The three types of muscle contractions are concentric, eccentric, and isometric. In every contraction, the actin and myosin are interacting in the sarcomere to pull the fibers and contract the muscle. The sliding filament theory states that the myosin is actually staying in place, and the actin is contracting together and lengthening apart to create the length-tension relationship. For every contraction

However Bax (pro-apoptotic gene) interact with mitochondria voltage-dependent ion channel, release the cytochrome c. p53 can regulate the expression levels of Bax and promote cell apoptosis. P53 also can induce apoptosis by the receptor protein signal pathway, TNF receptor and the Fas protein. After DNA

If you can prolong your life, and make yourself feel better about who you are then why not overcome this overweight issue. In today’s world we are facing an epidemic that seems to be affecting even are young at an early age. We all know that obesity can have adverse effects on health, well-being, and relationship, and can be solved by eating organic food, exercising, and discipline. We are here to find out the different causes of obesity, and find out what we can do to overcome this fast growing

Devipriya: Reproductive Specialist (Reproduction, Speciation & Symbiosis) Sarina: Epidemiologist (Human Disease, Vector Control & Virus/Phage) Is it possible to have a bacterial infection that selectively kills males? If so, explain the biology. How has this strange biology propagated throughout the species? The illness does not respond to any known treatments. As biologists, how might you stop the spread of this disease? Devipriya/Sarina Briefly describe the basic biology of Wolbachia. What

cells were harvested, lysed, and the protein concentrations were quantified using a Bio-Rad protein assay as described in a previous study [You et al., 2017]. In a parallel experiment, the mitochondrial and cytosolic fractions were isolated using a mitochondria isolation kit according to the manufacturer’s instructions. For Western blotting, equal amounts of protein samples were electrophoretically transferred onto polyvinylidene difluoride membranes (Schleicher & Schuell, Keene, NH, USA) following electrophoretic
