The energy used to pump hydrogen ions from the mitochondrial matrix across the inner membrane and into the intermembrane space i
Romashka-Z-Leto [24]

Answer:

b. reactions in the electron transport chain

Explanation:

Oxidative phosphorylation, which is the process described in this question, is the third stage of cellular respiration which occurs in the MITOCHONDRION of eukaryotic cells. In this stage of oxidative phosphorylation, which encompasses electron transport chain (ETC) and chemiosmosis, ATP is synthesized.

The ATP is synthesized when protons (H+) move from the mitochondrial matrix into the intermembrane space, forming, a proton pump. The series of electron transfers (reactions) that occur in the complexes of the ETC provides the ENERGY to pump the protons/hydrogen ions out of the matrix, which creates the electrochemical gradient required for ATP synthesis with the help of ATP synthase.

artcher [175]

Answer:

Can you provide a picture maybe? The tail-like structure is a flagella if that's what you're asking, but many bacteria have that. I'm guessing flagellum off of what's provided, but I'm not sure without an an image.

Which term best describes the interval between the birth of the newborn and the return of the reproductive organs to their norma
kodGreya [7K]

Answer:

B. Puerperium, or fourth trimester of pregnancy

Explanation:

  • Puerperium or the fourth trimester of pregnancy is also known as the postpartum period.
  • This period starts immediately after the mother gives birth to a child.
  • During this period the size of the uterus and other reproductive organs along with the hormone levels return to their normal state.
  • It is the phase where regression of all the anatomical and physiological changes that took place i in the reproductive organs of the females takes place.
  • This phase is divided int three periods -

1. Immediate puerperium, or the first 24 hours after parturition

2. Early puerperium, which extends until the first week postpartum;

3. Remote puerperium, which includes the period required for involution of the genital organs and return of menses, usually approximately 6 weeks.

  • This phase is highly critical for the mother as this requires rest and proper care as there are risks of bleeding. Therefore, the midwife or the nurse must take proper care of the mother.
