Pex7p Transport Role As previously stated‚ the location of the mutation causing the lethal RCDP1 phenotype has been narrowed down to the 10-exon PEX7 gene. wt PEX7 is translated as a cytosolic import receptor Pex7p‚ responsible for binding enzymes destined for the peroxisomal matrix marked by the N-terminal peroxisome-targeting signal 2 (PTS2). In a normal cell‚ the Pex7p receptor has a PTS2 receptor region that recognizes and binds the PTS2 of the localized protein in the cytosol‚ necessary for

Lab 9 Report: Exercise Physiology Introduction When the human body is put to work and undergoes any sort of activity‚ it requires more energy and resources in order to sustain this. The cells in muscles and organs must work faster‚ and thus require more energy to do so. The body compensates by increasing heart rate and respiration in order to increase the amount of oxygen entering‚ carbon dioxide leaving‚ and rate at which these gases are delivered to cells throughout the body. In this lab‚ we

Chapter 37: Water and sugar transport in plants Water moves from areas of high water potential to areas of low water potential. Water’s potential energy in plants is a combination of (1) it’s tendency to move in response to differences in solute concentration and (2) the pressure exerted on it Plants do not expend energy to replace water that is lost to transpiration when stomata are open and photosynthesis is occurring. Instead‚ water moves from soil and roots to leaves long a water potential

Active and passive transport are biological processes that move oxygen‚ water and nutrients into cells and remove waste products. Active transport requires chemical energy because it is the movement of biochemicals from areas of lower concentration to areas of higher concentration. On the other hand‚ passive trasport moves biochemicals from areas of high concentration to areas of low concentration; so it does not require energy.
