主动转运Active transport:movement across the membrane is mediated by a macromolecule.①It is a saturable process②It is selective for chemical structure③It requires metabolic energy④It transport molecules against a concentration gradient. pH吸收部位A low pH inhibits ionization of a weak acid and enh...
These transport oxygen molecules throughout the body, and also give blood its colour (from the hemoglobin protein within, which turns red when combined with oxygen). Red blood cells, as with all cells in the human body, have a limited operating life. They are produced within the marrow of ...
Other types of cell transport that require energy involve vesicles. Vesicles are small sacs that are produced from the cell's Golgi apparatus. They collect waste products which they expel from the cell by fusing with the cell membrane, though they can also be used to collect molecules that are...
How does passive transport benefit a cell? What provides energy for a cell? What are cilia in animal cells? What part of the cell lets things in and out? What facilitates passive transport across a cell membrane? What organelles are membrane sacs used to transport molecules?
How are molecules transported across a cell membrane? Which type of molecule will require some amount of energy to cross the cell membrane? The lipid bilayer molecules do what for the cell? What is bulk transport cell membrane? Which macromolecules make up the plasma membrane? What are t...
Respiration and photosynthesis are both energy conversion processes. In respiration chemical energy is converted from one form to another while photosynthesis produces chemical energy from light energy. Both processes are dependent on the transport of charged particles across a membrane. ...
A glucose molecule is broken down into two pyruvic acid molecules in which stage of cellular respiration? A. Glycolysis. B. The citric acid cycle. C. Gluconeogenesis. D. The electron transport system. What are the gross and net products of each step of Cellular respiration? Fill in the...
In fact, these traits are precisely what make a cell a cell. What Defines a Cell? Figure 1: Transport proteins in the cell membrane A plasma membrane is permeable to specific molecules that a cell needs. Transport proteins in the cell membrane allow for selective passage of specific ...
What are semi-autonomous organelles? Organelles and the Nucleus: Organelles are subcellular structures that perform a variety of functions including (but certainly not limited to) protein and lipid synthesis, respiration (as seen in animal cells), and photosynthesis (as seen in plant cells).
