Select the true statements about protein secondary structure. The β‑pleated sheet is held together by hydrogen bonds between adj

acent segments. In a β‑pleated sheet, the side chains are located between adjacent segments. In an α‑helix, the side chains are located on the outside of the helix. The secondary level of protein structure refers to the spatial arrangements of short segments of the protein. Disulfide bonds stabilize secondary structure.

<h3>What Is the Pathway of Blood Through the Heart?</h3>

There are four chambers in the human heart.

Mammals and birds have double circulation.

The pathway of blood through the heart is as follows:

  • The deoxygenated blood from the body is received in the right atrium from the vena cava and enters the right ventricle through a tricuspid valve. It enters the pulmonary artery through the semilunar valve and goes to pulmonary circulation.
  • The oxygenated blood from the lungs is received in the left atrium from the pulmonary veins and enters the left ventricle through the bicuspid valve. It enters the aorta through a semilunar valve and goes to the systemic circulation.

Lyrx [107]
The main function of white blood cells is to help protect the human body from infection as well as other foreign materials. White blood cells are also known as leukocytes, and they develop in bone marrow from stem cells. There are five different types of white blood cells<span>, including neutrophils, lymphocytes, monocytes, eosinophils and basophils.</span>

What is water’s role in the light reaction of photosynthesis?
notsponge [240]

The correct answer is - Its electrons are used to form NADPH.

On receiving light energy, electrons are expelled from the reaction center of photosystem II. The expelled electrons finally reduces oxidized NADH⁺ to NADH. The oxidized reaction center of photosystem II split water into protons, electrons and oxygen. The electrons released from water reduces oxidized reaction center of photosystem II. Thus, oxidized reaction center of photosystem II gets back its expelled electrons. Therefore, electrons from water forms NADH.
