A chemical reaction occurs only when the collision between the reacting molecules takes place. However, not all the collisions are efficient in making the reaction. The products are produced only when the molecules colliding exhibits a certain kind of minimum energy known as threshold energy.
The threshold energy refers to the least amount of energy needed for the reactants to collide effectively, and to produce the activated complex. It is kinetic energy in supplementation with the energy of activation. Hence, threshold energy is more in comparison to the activation energy.
I'm quite sure it's activity level. One other thing that could've been said is metabolism, but that isn't there. However, food is consumed for the body to have energy, and without that energy we wouldn't be able to function. And when we let that intake of food settle, it's stored as fat. But because of activity level, we are capable of burning those calories.
D is the answer you are looking for. <span />
Answer:
covalent bonds
Explanation:
Nitrogen atoms will form three covalent bonds (also called triple covalent) between two atoms of nitrogen because each nitrogen atom needs three electrons to fill its outermost shell.
(if it is still confusing i have another way of explaining so jus let me know :)
0,26mol ------- 13g
1mol ------- x
x = (13g*1mol) / 0,26mol = 50g
It could be Ti or V
Answer: 1. h oxidized, 2. g reduced, 3. e glucose, 4. c pyruvate, 5. b NAD+, 6. a NADH.
Explanation:
Glycolysis is also known as Embden-Meyerhof pathway, and in this process one mole of glucose is oxidised into two moles of pyruvate in a series of enzyme-catalyzed reaction and do not involve molecular oxygen i.e. oxygen indepenedent process. This process is studied in two phases preparatory (energy-investment) and pay-off phase(energy generation).
Net reaction: Glucose + 2NAD+ HPO4-2 = 2 Pyruvate + 2NADH + 2ATP + 2H2O.
