Glycolysis provides a cell with a net gain of 2 ATP molecules and 2 NADH molecules.
Glycolysis is the first step in cellular respiration, and it is a series of chemical reactions that break down glucose into pyruvate. The first half of glycolysis requires the input of 2 ATP molecules, but the second half produces 4 ATP molecules. However, 2 of these ATP molecules are used to rephosphorylate the intermediates of glycolysis, so the net gain of ATP is 2.
In addition to ATP, glycolysis also produces 2 NADH molecules. NADH is a coenzyme that carries electrons, and it is used in the electron transport chain to generate ATP.

b. amphetamine
c. phencyclidine
d. barbiturate
I believe it’s a or c
The primary products of the light independent reactions (after one turn of the cycle) are:
a) two G3P molecules
b) three ADP
c) two NADP+
However ADP and NADP+ are not really "products". They are regenerated and later used again in the Light-dependent reactions. Each G3P molecule is composed of three carbons.
For the Calvin cycle (Light independent cycle) to continue, 5 out of the 6 carbons provided by the two G3P molecules are used to regenerate ribulose 1, 5 phosphate. Therefore there remains only one carbon for the next turn of the cycle.
One molecule of glucose requires 6 turns of the cycle. Any extra G3P is used to make starch, sucrose and cellulose.

Answer:
A,C,D,E
Explanation:
Answer:
There are only four parts of skill related fitness in the options; they are:
Speed
Agility
Balance
Coordination
Explanation:
Physical fitness refers to the ability to perform physical activities well without fatigue. In other words, being physically fit refers to a state of general wellbeing. Physical fitness can either be health-related or skill-related. The skill-related components are six in number viz: agility, power, balance, coordination, speed and reaction time.
However, only four of these skill-related parts of physical fitness are mentioned in the options of this question. They are:
- Speed: This refers to the ability to run a distance in a short time frame.
- Agility: This is the ability to move easily and quickly in different directions
- Balance: The ability to maintain an upright body position during training or physical activity
- Coordination: The ability to make physical senses of one's body (eye) cooperate with the limbs (hands and feets) during a physical activity.
Note that, Aerobic Endurance and Muscular strength are health-related components of fitness
The five components of skill-related fitness are Speed, Coordination, Agility, Balance, and Muscular Strength. Each plays a different role in physical activities and sports.
The five parts of skill-related fitness are; Speed, Coordination, Agility, Balance, and Muscular Strength.
