Answer:
Vitamin C is one of the most important ingredient of skin as it play a key role in synthesis of collagen necessary for elasticity of skin.
Derivatives of vitamin C:
Following are derivatives of vitamin C used in medication for skin wrinkling and achne:
<span>1. Ascorbyl-6-palmitate
2. Magnesium ascorbyl phosphate
</span>
Derivatives of vitamin A:
There are four derivatives of vitamin A use in treating skin wrinkling, these are:
1.Retinol
2. Retinyl Palmitate
3. Retinaldehyde
3. Retinyl Retinoate
A. Pressure.. Because there is a lot of water going in the same direction
Answer:
Through simple diffusion, down the concentration gradient.
Explanation:
The phospholipids of the membrane are amphipathic with hydrophillic heads and hydrophobic tails. Other polar molecules cannot go through this hydrophobic interior. Since small uncharged lipids are non polar and hydrohobic, they are able to go through the membrane without the help of transport proteins. Therefore, the last two options can be ruled out because facilitated diffusion includes the use of a protein. Diffusion involves molecules moving down the concentration gradient so the second option can be ruled out.
Answer:
- GLYCOLYSIS :- Glycolysis is the metabolic pathway that converts glucose C₆H₁₂O₆, into pyruvic acid, CH₃COCOOH. The free energy released in this process is used to form the high-energy molecules adenosine triphosphate and reduced nicotinamide adenine dinucleotide
- PRODUCTS :- Glycolysis produces 2 ATP, 2 NADH, and 2 pyruvate molecules: Glycolysis, or the aerobic catabolic breakdown of glucose, produces energy in the form of ATP, NADH, and pyruvate, which itself enters the citric acid cycle to produce more energy.
- INPUT:- Glycolysis is the first step in cellular respiration, occurring in all living cells. Overall, the input for glycolysis is one glucose, two ATP and two NAD+ molecules giving rise to two pyruvate molecules, four ATP and two NADH.
- BREAKDOWN:- During glycolysis, glucose ultimately breaks down into pyruvate and energy; a total of 2 ATP is derived in the process (Glucose + 2 NAD+ + 2 ADP + 2 Pi --> 2 Pyruvate + 2 NADH + 2 H+ + 2 ATP + 2 H2O). The hydroxyl groups allow for phosphorylation. The specific form of glucose used in glycolysis is glucose 6-phosphate
- STAGES:-
- Reaction 1: glucose phosphorylation to glucose 6-phosphate.
- Reaction 2: isomerization of glucose 6-phosphate to fructose 6-phosphate
- Reaction 3: phosphorylation of fructose 6-phosphate to fructose 1,6-bisphosphate
- Reaction 4: cleavage of fructose 1,6-bisphosphate into two three-carbon fragments.
