Human Fertilization Process

How many chromosomes does each human gamete typically contain?

• 46 chromosomes

• 12 chromosomes

• 92 chromosomes

• 23 chromosomes

What is the primary function of the acrosome reaction during fertilization?

• To initiate the cortical reaction

• To fuse the sperm and egg nuclei immediately

• To digest the outer layers of the egg, allowing sperm entry

• To provide energy for the sperm to swim towards the egg

What marks the location where fertilization typically occurs within the female reproductive system?

• Outside the body

• In the uterus

• In the fallopian tube

• In the ovary

Which enzyme plays a crucial role in allowing the sperm to penetrate the egg during the acrosome reaction?

• Protease

• Lactase

• Amylase

• Lipase

What does the ZP stand for in the context of the cortical reaction?

• Zygomatic process

• Zonal polarity

• Zygote placement

• Zona pellucida

What is the main purpose of the cortical reaction in human fertilization?

• To release nutrients for the embryo

• To prevent additional sperm from entering the egg

• To initiate cell division in the zygote

• To increase the mobility of the sperm

How does the cortical reaction contribute to the prevention of polyspermy?

• By digesting all surrounding sperm

• By speeding up the sperm's movement

• By hardening the outer membrane of the egg

• By increasing the temperature around the egg

Following fertilization, what is the next major process that occurs as the zygote develops?

• Photosynthesis

• Meiosis

• Mitosis

• Binary fission
