Title: How does a zygote respire and metabolize before implantation? Post by: Goat720 on Jul 1, 2022 Our cells respire and metabolize with the help of blood yes? How does a zygote respire and metabolize before implantation?
Title: Re: How does a zygote respire and metabolize before implantation? Post by: bio_man on Jul 1, 2022 In order for a zygote to grow within a human, it needs to be implanted somewhere along the uterus wall. The implantation allows it to extract nutrients and oxygen from the host.
Does that help? Title: Re: How does a zygote respire and metabolize before implantation? Post by: Goat720 on Jul 2, 2022 But isn't it dividing as it's making its way down the fallopian tube? I figured it would need oxygen and nutrients to do this.
