对偶婚制的定义 抚养的定义
A.
对偶婚制是成对男女在或长或短的时期内相对稳定的偶居。在对偶婚制下，一个男子在许多妻子中有一个主妻，而他对于这个女子来说，也是她的许多丈夫中的一个主夫，这对主要的丈夫和妻子在一定时期里共同生活，组成最初的对偶家庭，但这种家庭本身还很脆弱，没有自己的家庭经济，也不可能成为社会经济的细胞组织，而且婚姻关系极不牢固，可以根据任何一方的意愿而解除。这种家庭仍以女性为中心，实行族外婚的原则和女"娶"男"嫁"，夫从妇居的婚姻居住方式，妻子定居于本民族，丈夫则来自于别的民族，所生子女属于民族，世系按计算，对偶婚制是继群婚制而出现的一种婚姻家庭制度，是从群婚制到一夫一妻的过渡形式。
B.
抚养，主要是父母、祖父母、外祖父母等长辈对子女、、外等晚辈的抚育、教养。

【多选题】How is acetyl groups transfered via shuttle from mitochondria to the cytosol?
A.
The inner mitochondrial membrane is impermeable to acetyl-CoA, so an indirect shuttle transfers acetyl group equivalents across the membrane. Intramitochondrial acetyl-CoA first reacts with oxaloacetate to form citrate, in the citric acid cycle reaction catalyzed by citrate synthase.
B.
Citrate then passes through the inner membrane on the citrate transporter. In the cytosol, citrate cleavage by citrate lyase regenerates acetyl-CoA and oxaloacetate in an ATP-dependent reaction.
C.
Oxaloacetate cannot return to the mitochondrial matrix directly, as there is no oxaloacetate transporter. Instead, cytosolic malate dehydrogenase reduces the oxaloacetate to malate, which can return to the mitochondrial matrix on the malate–α-ketoglutarate transporter, in exchange for citrate.
D.
In the matrix, malate is reoxidized to oxaloacetate to complete the shuttle. However, most of the malate produced in the cytosol is used to generate cytosolic NADPH through the activity of malic enzyme. The pyruvate produced is transported into the mitochondria by the pyruvate transporter, then converted back into oxaloacetate by pyruvate carboxylase in the matrix.
