Metabolism 4: what do we gain?

  • 2 ATP from glycolysis
  • 2 ATP from 2 cycles of the citric acid cycle
  • 4 ATP from the 2 NADH molecules generated through reduction during glycolysis
  • 24 ATP from the 8 NADH molecules that enter the electron transport system
  • 4 ATP from the 2 FADH molecules
This makes up a total of 36 ATP molecules.

[see Metabolism 1-3 for processes of glycolysis, citric acid cycle and electron transport system]

Growth and Development 2: Placentation and Hormones

How does the placenta form? The placenta forms from the embryonic trophoblastic/mesoderm tissues, as well as the maternal endometrial tissues. Vessels develop in the embryonic tissues which then supply nutrients to the foetus from the maternal blood supply. The chorion develops fingerlike villi which have become vascularised and extend to the embryo as umbilical arteries and veins. The embryo, amnion and yolk sac float in a fluid-filled chamber attached to the placenta by a body stalk. The placenta grows and begins to develop into organised regions, bulging into the uterine cavity as it grows. It becomes fully developed by the end of the third month (end of first trimester), where the foetus moves farther from the placenta connected by the umbilical cord. By 12 weeks, the placenta is providing nutrients and removing wastes, meaning it takes on the role of oestrogen and progesterone which used to be released from the corpus luteum. Decidua capsularis: endometrium surroundi...

Growth and Development 4: Labour, foetal circulation and lactation

What happens when we give birth? During the last week of pregnancy, oestrogen reaches a peak. This causes myometrial weakness and irritability. Then, weak 'Braxton Hicks' contractions occur, which become uterine contractions stimulated by oxytocin and prostaglandins closer to birth. Emotional and physical stress establishes a positive feedback mechanism with the hypothalamus, increasing oxytocin release. The stages of labour are summarised below:   1.   Dilation Stage (8 hours) Onset of labour Cervix dilates Foetus moves towards birth canal Contractions begin and increase in frequency Water eventually breaks   2.    Expulsion Stage (2-3 hours) Cervix pushed open by foetus Contractions increase in intensity, frequency and length Continues until foetus emerges from vagina (delivery) Surgical intervention possible: episiotomy (cutting of perineal membrane) or caesarean section Newborn health assessed immediately   3.   Plac...

Lymphatics and Immunity 3: Cell-Mediated Immunity

What is adaptive immunity then? Adaptive or specific immunity responds to specific antigens through the coordinated action of T and B cells. It is only developed after birth. Adaptive immunity involves both cell-mediated and antibody-mediated immunity. Cytotoxic T cells provide cell-mediated immunity, providing defence against abnormal cells and pathogens inside  cells. B cells provide antibody-mediated immunity, providing defence against antigens and pathogens in body fluids. There are four properties of immunity: Specificity - response to only a specific type of antigen Versatility - production of many types of lymphocytes Memory - active lymphocytes stay in circulation and provide immunity against new exposure Tolerance - immune system ignores normal antigens What is cell-mediated immunity? T cells only recognise antigens that are bound to glycoproteins in a plasma membrane. These are termed major histocompatibility complex proteins. These proteins differ betwee...
