Fractionation of carbon isotopes in oxygenic photosynthesis be less fractionated in C (ie, δC is relatively less negative) compared to C3 plants with low water-use efficiency. C4 plants have developed the C4 carbon fixation pathway to conserve water loss, thus are more prevalent in hot, sunny, and dry climates. These plants differ from C3 plants because the Calvin Cycle in C4 plants produces a four-carbon molecule, malate (rather than 3-phosphoglycerate), after fixation of CO. Malate, the four-carbon compound is the namesake of "C4" photosynthesis. This pathway allows C4 photosynthesis to efficiently shuttle CO to the RuBisCO enzyme and maintain high concentrations of CO within bundle sheath cells.
Need for Speed: Undercover that sort. Chase Linh will tell you [what] you need to do to get on the inside of a racing group in order to get dirt on them, and then after a race she'll say 'We have enough, let's move in.' [But you're left asking: How did that help at all?]" Finally, the in-game frame rate received little praise, and GameSpot particularly criticized the PS3 version for this problem resulting in a lower score on the platform compared to the Xbox 360 and PC versions. "Need for Speed: Undercover" has sold 1.4 million copies in the United States. Need for
