Products of the Krebs Cycle

1. carbon dioxide 2. 2 atp 3. NADPH

the order of the three stages of aerobic cellular respiration

1. glycolysis 2. krebs cycle 3. electron transport

formula for cellular respiration

C6H12O6 + 6 O2 -> 6CO2 + 6H20 + ATP ENERGY

the second step of aerobic cellular respiration is called the _______________ and it takes place in the _______________ and it requires ___________________

Kreb's cycle mitochondria oxygen

how is energy produced in a cell?

a phosphate is added to ADP to produce ATP while a phosphate is removed from ATP to produce ADP and release energy

muscle cells can carry out either aerobic cellular respiration or lactic acid fermentation. list and explain 2 reasons why they usually rely on aerobic rather than anaerobic.

aerobic makes more atp 36-38 anaerobic makes lactic acid which makes muscles sore

when pyruvate is converted to carbon dioxide and ethanol, it is called __________________

alcoholic fermentation

cellular respiration without oxygen is_________

anaerobic respiration

the goal of cellular respiration is to create _____________

atp

fad and nad+ molecules are needed for the breakdown of each glucose molecule, so why do you think the recommended allowance is so small v.s. that of glucose?

because they're recycled they are not used up and they keep doing their jobs

compare and contrast Photosynthesis and Cell respiration- WHAT DO THEY BOTH HAVE IN COMMON

both: -Uses high energy electron carriers -Have a cycle of chemical reactions to make ATP -Have electron transport in membranes

What are the products of aerobic cellular respiration?

carbon dioxide, water, and atp

compare and contrast Photosynthesis and Cell Respiration - CELLULAR RESPIRATION

cellular respiration: -Glucose/food is broken down -Sugar energy is used -Products= C02 & H20 are produced -Reactants=02 & C6H1206 -Occurs in mitochondria of plant & animal -Doesn't need light

oxygen gas production will happen within me (m or c)

chloroplast

i can be found in plant cells (m or c)

chloroplast and mitochondria

i would be found within a photosynthetic protists (m or c)

chloroplast and mitochondria

glucose production will happen within me (m or c)

chloroplasts

i contain chlorophyll(m or c)

chloroplasts

the calvin cycle happens within me (m or c)

chloroplasts

what is another name for the kreb's cycle?

citric acid cycle

where does the first step of cellular respiration take place?

cytoplasm

what happens when you remove a phosphate group from atp?

energy is released

what happens during the electron transport chain?

energy is transferred from NADH and FADH2 to ATP

if there is no oxygen present, cells can still produce energy through a process called ____________

fermentation

what does cell respiration start with?

glucose

what are the reactants used in aerobic cellular respiration?

glucose and oxygen

what process converts glucose to pyruvate?

glycolysis

in aerobic cellular respiration, what three major steps are involved?

glycolysis(cytoplasm) Krebs cycle(mitochondria) ETC(mitochondria)

explain in detain the net gain of atp molecules per glucose molecule at each of the 3 stages of aerobic cellular respiration and a net total

glycolysis- 2 atp Krebs cycle- 2 atp electron transport- 32-34 atp total- 36-38 atp

where does lactic acid fermentation occur?

in our muscles

what are the two kinds of anaerobic respiration?

lactic acid fermentation alcoholic fermentation

what are 2 types of fermentation? how do they differ? how are they similar? give examples of each what type of organisms use each

lactic acid: lactic acid happens in muscles example- cells and bacteria alcoholic fermentation: produces c02 and ethanol example- yeast similar- glycolysis

in photosynthesis what are the two major reactions that take place?

light dependent reaction(thylakiod) calvin cycle(stroma)

Krebs and the Electron Transport Chain both happen within me (m or c)

mitochondria

My main goal is to produce a lot of ATP energy (m or c)

mitochondria

carbon dioxide gas production will happen within me (m or c)

mitochondria

i am the site of aerobic cellular respiration (m or c)

mitochondria

i can be found in animal cells (m or c)

mitochondria

muscle cells would contain a lot of me (m or c)

mitochondria

water production will happen within me (m or c)

mitochondria

does the first step of cellular respiration require energy?

no

explain why organisms that release energy through aerobic cellular respiration need oxygen. what will happen if there isn't enough oxygen present?

oxygen is needed to complete electron transport not enough? gets part of way through krebs- stops- switches to fermentation

compare and contrast Photosynthesis and Cell Respiration- PHOTOSYNTHESIS

photosynthesis: -Food(glucose) is made -Energy from the sun is used and stored -Products= 02 & C6H1206 -Reactants= C02 & H12 used up -Occurs in Chloroplast -Needs Sunlight

explain in detail how prokaryotic organisms complete the process of cellular respiration. is it more or less energy efficient then eukaryotic organisms? if so, why?

prokaryotes have no mitochondria, in cellular respiration it has a mitochondria and electron transport happens in the cell membrane and produces 32 atp

a plants root cells don't contain chloroplasts, so they can't carry out photosynthesis. explain how root cells get the energy they need to live

root cells have a lot of mitochondria uses glucose and oxygen (leaves) to make atp

compare and contrast aerobic and anaerobic cellular respiration

sim: produces energy breaks down glucose glycolysis happens diff: aerobic uses oxygen- 02 produces 36-38 atp anaerobic- no 02 produces 2 atp, Krebs cycle and electron transport (fermentation)

the third step of aerobic cellular respiration is__________________ and it occurs in the __________________ and it needs________________________

the electron transport chain mitochondria oxygen

what happens when an organism that needs oxygen is placed in an environment without oxygen?

the electron transport chain stops which then stops the kreb's cycle

FADH2 and NADH are co-enzymes and their job is to____________

transfer electrons

explain in detail the ingredients involved in making bread. explain in detail how the by-products of cellular respiration used by yeasts makes them useful in the process of making bread

you need yeast and h20 and sugar and flour and salt alcohol ends up evaporating c02 makes the bread rise
