Question 4 options:

Oxygen

NADH

ATP

Pyruvate
Question 5 (1 point)

What is the benefit of oxidative phosphorylation over glycolysis?
Question 5 options:

Much more ATP produced

No membrane required

No special organelle required

Produces oxygen
Question 6 (1 point)

Why does photosynthesis require 38 ATP to make sugar but respiration only creates around 32 ATP?
Question 6 options:

Plants need more energy for building cell walls than animals do for respiration

Useful energy is lost during each chemical change

The sugar made from photosynthesis has more energy than the type of sugar used for respiration

All of the above

Within the Cell wall

Throughout the Cytoplasm

Within the mitochondria

Outside the chloroplast
