Question: In the malate–aspartate shuttle, electrons from NADH are transferred to _____________, forming malate. Group of answer choices oxaloacetate aspartate acetate glutamate None of the above. WebTransporter systems. The high-affinity glutamate/aspartate transporter (GLAST, also named EAAT1) is present in Müller cells and serves to maintain a low concentration (<1 μM) of glutamate in extracellular space. It utilizes the gradients of Na+, K +, and H + across the plasma membrane to transport glutamate into cells.

WebOxaloacetate (OAA, HOOC-CO-CH 2-COOH) is a TCA cycle intermediate.It precedes citrate which is formed by the transfer of an acetyl group to OAA. OAA is formed by the deamidation of aspartate or condensation of CO 2 with pyruvate or PEP. Since mammals do not possess the enzymatic machinery to form TCA cycle intermediates from acetyl … WebAug 28, 2024 · Aspartate aminotransferases are found in the liver, heart, and muscles and red blood cells.
