Which of the following fat-soluble vitamins is an antioxidant necessary for synthesizing visual pigments, can be found in butter and leafy green vegetables, and can lead to blindness when a person's diet is deficient in it? a. Vitamin D
b. Vitamin A
c. Vitamin K
d. Vitamin E

Answers

The correct answer is B. Vitamin A.

Vitamin A (retinol, retinoic acid) is a fat-soluble vitamin important for vision, growth, cell division, reproduction and immunity. It also has antioxidant properties.

Vitamin A is present in many foods, such as spinach, dairy products and liver. Other sources are foods rich in beta-carotene, such as leafy vegetables, carrots and cantaloupe. Your body transforms beta-carotene into vitamin A.

There are two dofferent types of vitamin A. The first type, preformed vitamin A, it is found in beef, poultry, fish and dairy products. The second type, provitamin A, is found in fruits,vegetables and other products of vegetable origin. The most common type of provitamin A present in foods and dietary supplements is beta-carotene.

Not consuming enough vitamin A, can cause diseases (which can be avioded with a good diet). Vitamin A plays a very important role in vision. On the one hand, it is essential for the production of the pigment consumed by photoreceptors responsible for vision in darkness. Therefore, low levels of vitamin A lead to night blindness.

MULTIPLE CHOICE WILL MARK BRAINLIEST Read the following statements that describe what happens as an impulse travels. What is the correct order in which the steps occur?

1) The impulse continues to travel down the axon away from the cell body.
2) Na+ gates close and K+ ions flow back out of the cell restoring the resting potential.
3) Gated K+ and Na+ channels are closed. The inside of the cell is slightly negative compared to the outside.
4) The neuron receives a stimulus great enough to start an impulse.
5) Gated Na+ channels open. The net movement of Na+ ions into the cell produces the action potential.
