WHICH OF THE FOLLOWING GLUCOSET TRANSPORTER PROTEINS IS CONSTITUTIVELY EXPRESSED IN THE PLASMA MEMBRANE OF PANCREATIC ALPHA AND BETA CELLS?
1. GLUT 1 2. GLUT 2 3. GLUT 3 4. GLUT 4 |
GLUT TWO
|
|
WHAT TYPE OF CELLS ARE OPEN ALL THE TIME THAT
TRANSPORT GLUCOSE (KNOWN AS A TRANSPORT PROTIEN) ACROSS THE CELL MENBRANE. NARROW PASSAGE WAY THAT ALLOW THAT ALLOW A SMALL AMOUNT OF GLUCSOSE MOLECULES TO TRANSPORT ACROSS THE MENBRANE. |
GLUT ONE
REQUIRES NO ENERGY AND IS NOT ACTIVE TRANSPORT |
|
is the insulin-regulated glucose transporter found in adipose tissues and striated muscle (skeletal and cardiac) that is responsible for insulin-regulated glucose
trans location into the cell. This protein is expressed only in muscle and fat cells, the major tissues in the body that respond to insulin |
Glucose transporter type 4, also known as GLUT4,
|
|
NAME TWO GLUT PROTEINS THAT ARE PRESENT IN EVERY CELL
|
GLU 1 AND GLU 3
|
|
WHAT GLU CELL FUNCTIONS WITH HIGH CAPACITY , AND FOUND IN THE CELL MENBRANES OF LIVER AND PANCREATIC ALPA AND BETA CELLS THAT RELEASE THESE PROTEINS . COMPLETELETY UNRESCRITED
|
GLU 2
|
|
ALLOWS GLUCOSE TO COME INTO THE CELL FASTER, FOUND IN HEPATOCYCTES, (ADIPOSE TISSUE), IN SKELETAL AND CARDIAC MUSCLES
KNOWN AS THE INUSLINE REGULATOR AND GLUCOSE STORAGE |
GLU 4
|
|
WHAT HAPPENS WHEN NO INSLUIN ?
|
GLU 4 IS PRODUCE IN THE INTERIOR OF MUSCLE AND FAT CELLS
BRINGS INSULIN FROM STORAGE WHICH IS GLYGEON |
|
Also known as the respiratory chain. It is composed of the mitochondrial enzymes (also known as complexes I, II, III and IV) that transfer electrons from one complex to another, eventually resulting in the formation of ATP.
|
ELECTRON TRANSPORT CHAIN
|
|
Components of the electron transport system include complexes I, II, III, and IV, plus two individual molecules, coenzyme Q and cytochrome c.
|
COMPONENTS OF ECT
|
|
WHAT IS THE cell's metabolism process
|
it must manufacture the energy
|
|
two metabolic pathways that lead up to the making of ATP
|
Glycolysis
Krebs Cycle |
|
WHAT IS THE BY PRODUCT OF GLYCOLYSIS AND KREBS CYCLE
|
areNADH is a product of both these processes, whereas FADH2 is a product of the Krebs cycle
|
|
energy fuel of the cell
|
The cell respiration process is designed to produce ATP--also known as adenosine triphosphate--
|
|
Both NADH and FADH2 are involved FOR ?
|
in the cell respiration process
|
|
NADH and FADH2
|
the energy (charge) needed to convert O2 molecules into H2O.
|
|
Integral membrane provide proteins work with NADH and FADH2 to create
|
the pressure needed to move H2 molecules through the mitochondria membrane.
|
|
Once the H2 molecules enter into the mitochondria, WHAT HAPPENS
|
ATP synthesis, or ATP production can begin.
|
|
The electron transport chain begins with
|
reoxidizing NADH to form NAD+ and channeling the electrons into the formation of reduced coenzymes
|
|
WHO TRANFERS THE 2 ELECTRONS NEEDED
|
NADH
|
|
WHAT DOES COMPLEX ONE DO?
|
accepts electrons from NADH and
serves as the link between glycolysis, the citric acid cycle,fatty acid oxidation and the electron transport chain |
|
FUNCTIONS OF COMPLEX I
|
1. TRANSFER 2 ELECTRONS FROM NADH
WHICH WAS REDUCE TO FORM NAD 2.THEN PUMPS ONE H+ ION FOR EACH ELECTRON ACROSS THE INNER MENBRANE |
