If the Blessed sacrament is within a closed tabernacle it is proper to genuflect, or in some circumstances make a reverential bow. When the Blessed Sacrament is exp[osed
for Eucharistic Adoration one should kneel on both knees upon entering or leaving the area

You are probably talking about the prayer of Consecration.This is when the priest invokes God's blessing on the elements (the bread and wine) and they are believed to become the Body and Blood of Christ.
Roman Catholic AnswerPrayer before the Blessed Sacrament for an extended period is called Adoration, and carries several indulgences. As the Blessed Sacrament is the physical presence of Jesus Christ, Body and Blood, Soul and Divinity, it is a priviledged place to pray. Many Churches, if they are large enough, have a separate chapel just for the Blessed Sacrament. All Catholic Churches should have the Blessed Sacrament in a central location with a lamp or oil or a candle burning all the time.The Act of Charity is sometimes given as a penance. It is one of the three acts of the Theological Virtues, which one should recite before beginning a meditation or private prayer in front of the Blessed Sacrament.

The Blessed Sacrament is the consecrated host (circular piece of unleavened bread) which is the body, blood, soul, and divinity of Jesus Christ, second person of the Trinity. Exposition of the Blessed Sacrament is a ceremony during which the Blessed Sacrament is set by the priest into a monstrance for adoration. The monstrance is a blessed, golden container used to hold the Blessed Sacrament. In its center is a circular space where the Blessed Sacrament, in a glass case, is set. Around this center is gold, usually sculpted into long thin pieces that radiate like light from the center where the Blessed sacrament is. This container for the Blessed Sacrament is held upright on a golden pedestal, which is part of the monstrance. During the ceremony called Exposition of the Blessed Sacrament, the priest exposes the host by setting it in the monstrance, and the monstrance is set on the altar in the church. Thus people can come and kneel and adore Jesus Christ in the Blessed Sacrament, which is held exposed in the monstrance.
The sacrament we are called to share in the life of the Blessed Trinity is Baptism.
