Cellular respiration

Metabolism

all chemical reactions in body

reduction

gain H. gain energy. catalyzed by enzymes

oxidation

loss of H. lose energy

The net gain of ATP from the complete metabolism of glucose if closest to

30

The formation of glucose from glycogen

gylcogenesis

Predict what would happen to ATP production if a virus pierced holes in the inner membrane of the mitochondria

ATP production would decrease because H+ gradient could not be established

Electron transport

Aerobic, H20, creates proton gradient, oxidative phosphorylation. 28 ATP

Which of the following are reduced during the Krebs cycle

NAD+ and FAD

catabolism

break down

What is an anabolic reaction? give example

build bigger things. amino acid formation

coenzymes

can act as an electron

Which of the following reactions would liberate the most energy

complete oxidation of a molecule of sucrose to CO2 and water

Oxidative

electron transport proteins form part of inner mitochondria membranes

Which part of the brain controls feeding behavior?

hypothalamus

glycolsis

in cytosol, glucose goes to fructose bisphosphate -2ATP substrate phosphorylation- 4ATP products- 2 pyruvate, 2NADH 02-> krebs cycle no o2-> lactic acid

Krebs

in mitochondria, pyruvate to actecol A, releases CO2 products- 2 CO2 + reduced coenzymes

What is the main function of cellular respiration

produce ATP

The end product of glycosis is

pyruvic acid

anabolism

reactions that build bigger things

What is form during aerobic respiration when electrons are passed down the electron transport chain?

water

gylcogenesis

glucose to glycogen

In addition to ATP, what is produced during cellular respiration

Co2, h2o

gulcogenesis

forming new glucose molecules from non carb molecules

glycogenolysis

glycogen to gulcose

When blood sugar levels drop ____ will occur in the liver as a response to the hormone glucagon

glycogenolysis

Substrate phosphorylation occurs during

gycolysis, krebs cycle

Which of the following best defines cellular respiration

oxidation of substances by which the energy is released in usable form to the cells.

Substrate level

phosphate group directly transferred from phosphorylated substates to ADP
