Astrophysics and Space Science Libraryty. In other words, when active transport of ions can be induced by the . of ATP by an ATPase, can transport of ions across a membrane in the direction of a thermodynamic gradient cause the . of ATP by the same ATPase? An affirmative answer to this question appeared to be the solution to the problemSLAY 发表于 2025-3-25 14:40:22

Late Transition Metal-Carboryne Complexesical sciences is comparable to the meaning of theoretical physics for the physical sciences. Theoretical physics, and especially mathematical physics, is concerned with the description of physical phenomena in mathematical terms. Beyond this, however, it makes abstractions from physical reality and悬挂 发表于 2025-3-26 05:36:38
Michael Baumann Dr., Radiologische Klinik quantum mechanical terms, of its supposedly fundamental unit, the atom. Although the atom presently is known not to be a fundamental but a composite particle, one can still consider the concept as basic for the description of matter. The properties of all substances can be explained in terms of the physics of this basic unit.过份 发表于 2025-3-26 10:36:59

Identification of Cool Iras Sourcesoften finds membrane fragments which are formed into closed vesicles from 300 to 500 Å in diameter. These vesicles are called . or . (Fig. 6.2). They retain most of the photosynthetic activity. Functional membrane fractions from cyanobacteria are more difficult to obtain. The photosynthetic apparatu
