The other guy is right, B is the answer now hurry and get that test prep done
<h2>
Answer:</h2>
Glucokinase or Hexokinase is a enzyme used at the first step of glycolysis.
<h2>
Explanation:</h2>
- Glucokinase is a Isoenzyme(enzymes which differs in the sequence of amino acids but catalyses the same reaction) of Hexokinase .
- Glucokinase (hexokinase D) is present only in liver and pancreas whereas hexokinase is present in all cells.
- In first step of glycolysis i.e formation of glucose-6-phosphate from glucose is completed with the help of hexokinase. In this step a ATP molecule is consumed i.e ATP is converted to ADP
Result: Glucokinase and hexokinase are used in the first step of glycolysis.
China. Their country has been rapidly growing for years.
Have a nice day!
Answer:
The Miller Urey experiment provide the first evidence that organic molecules needed for life could be formed from components.
Explanation:
Answer with explanation:
a. 3 sodium ions will move from inside to outside while 2 potassium ion will mover from outside to inside. This movement occur to maintain the gradient across the membrane
b. due to ion movement the concentration of sodium ions become higher outside the cell while the concentration of potassium ion will decrease
c. Due to 3 sodium ion movement outer change became positive (+).
d. due to ion movement the concentration of sodium ions become lower inside the cell while the concentration of potassium ion will increase inside
e. this change results in decrease in charge therefore charge inside the membrane becomes negative (-). See Solved Figure Attachment.
