The palisade mesophyll has long cylinder shaped cells, lots of chloroplasts, cells closely packed together and large size of cells.
The correct answers are;
A.) High energy sugars
A) ATP
The light-independent (dark) reactions are chemical reactions of photosynthesis which occurs within the stoma in plant chloroplast. These reactions use the products of light-dependent reactions which are ATP and NADPH with some enzymes (such as RuBisCO) to carry out its processes. Carbon dioxide and other compounds are converted to produce high energy sugars (glucose) which is used by the plant.
Glycolysis is the cellular degradation of the simple sugar (glucose) to produce pyruvic acid (also known as pyruvate), and ATP (adenosine triphosphate) is used as an energy source.
Answer:
Both facilitated diffusion and active transport are selective processes. Only selective molecules are allowed to cross the membrane. They utilize carrier proteins to move across the membrane.
Explanation:
Diffusion is the process by which molecules move across a membrane respective of the concentration gradient. The plasma membrane is a <em>selectively permeable membrane</em> which allows specific molecules to move across the concentration gradient.
Molecules migrate from a region of higher concentration to a lower concentration in case of diffusion. It can be classified into simple diffusion and facilitated diffusion. These are examples of <em>passive transport</em>.
In facilitated diffusion molecules move across the concentration gradient with the help of <em>carrier proteins or channel proteins</em>. The carrier proteins bind to the molecule which has to be transported and change conformation to allow it to cross the membrane. For example glucose molecule is carried across through <em>GLUT transporter</em>. <em>Channel proteins</em> open a channel inside the membrane and molecules get transported across the gradient.
Active transport carries molecules against the concentration gradient with the assist of energy. ATP hydrolysis is utilized to generate energy. As a result of active transport, the molecules are aggregated on one side of the membrane.
Explanation:
The enzyme is unchanged so that, it can be reused when more substrate is available.
