This may cause the carrier protein to change its shape, which moves the molecule or ion to the other side of the membrane. One way ATP powers active transport is by transferring a phosphate group directly to a carrier protein. As in other types of cellular activities, ATP supplies the energy for most active transport. In active transport, as carrier proteins are used to move materials against their concentration gradient, these proteins are known as pumps. Carrier proteins can work with a concentration gradient (during passive transport), but some carrier proteins can move solutes against the concentration gradient (from low concentration to high concentration), with an input of energy.
To move these molecules against their concentration gradient, a carrier protein is needed. Through its Primary Years (nursery school to year 5), Middle Years (years 6–10), and Diploma (years 11–12) Programmes, the focus is on creating a globally relevant education, with the integration of local contexts. Additionally, students at each Aga Khan Academy are instructed in both English and the national language, so they are able to work within their communities as well as around the world.įor more information on the International Baccalaureate, please visit the IB website.\)Īctive transport is the energy-requiring process of pumping molecules and ions across membranes "uphill" - against a concentration gradient. The programme is administered by the International Baccalaureate, a non-profit institution based in Geneva, Switzerland. The IB originated in Switzerland when teachers at the International School of Geneva, working with schools in Asia, Europe and the Americas, created the IB Diploma. The IB has come to be known not only for academic excellence but also for promoting pluralism – an understanding and appreciation of other cultures, languages and points of view. The International Baccalaureate programme provides international standards of evaluation, allowing students to pursue post-secondary education at world-class institutions of their choosing, with the skills for independent, creative thought and inquiry. It has become the curriculum of choice at international schools throughout the world. As a result, the Academies' Learner Profile exemplifies students and faculty that are open-minded, principled, reflective and inquiring individuals. The academic programme at the Aga Khan Academies was developed following the principles of the International Baccalaureate (IB), a world-class educational programme that emphasises rigorous, consistent schooling aligned to international standards.
